[edk2-devel] [PATCH 1/3] CryptoPkg/BaseCryptLib: add additional RSAEP-OAEP crypto functions

[edk2-devel] [PATCH 1/3] CryptoPkg/BaseCryptLib: add additional RSAEP-OAEP crypto functions

[Chris Ruffin via groups.io]

From: Chris Ruffin <v-chruffin@microsoft.com>

Expand the availability of the RSAEP-OAEP crypto capability in
BaseCryptLib.  Applications using RSA crypto functions directly from
OpensslLib can transition to BaseCryptLib to take advantage of the
shared crypto feature in CryptoDxe.

Pkcs1v2Decrypt(): decryption using DER-encoded private key
RsaOaepEncrypt(): encryption using RSA contexts
RsaOaepDecrypt(): decryption using RSA contexts

Re: [edk2-devel] [PATCH 1/3] CryptoPkg/BaseCryptLib: add additional RSAEP-OAEP crypto functions

[Li, Yi]

Hi Chris,

1. Please create a feature request BugZilla to introduce the background of the new API, such as purpose and application scenarios.
2. I took a quick look, the new API will make Pkcs1v2De/Encrypt support RsaContext input and the rest is same as old API right?

Regards,
Yi

Subject: [PATCH 1/3] CryptoPkg/BaseCryptLib: add additional RSAEP-OAEP crypto functions

From: Chris Ruffin <v-chruffin@microsoft.com>

Expand the availability of the RSAEP-OAEP crypto capability in BaseCryptLib.  Applications using RSA crypto functions directly from OpensslLib can transition to BaseCryptLib to take advantage of the shared crypto feature in CryptoDxe.

Pkcs1v2Decrypt(): decryption using DER-encoded private key
RsaOaepEncrypt(): encryption using RSA contexts
RsaOaepDecrypt(): decryption using RSA contexts

Re: [edk2-devel] [PATCH 1/3] CryptoPkg/BaseCryptLib: add additional RSAEP-OAEP crypto functions

[Chris Ruffin via groups.io]

Hi Yi, thanks for  your email.  I created a Bugzilla ticket for this, see Bugzilla ID #4732: https://bugzilla.tianocore.org/show_bug.cgi?id=4732.  The Pkcs1v2Encrypt() API is maintained but the implementation is refactored.  There is currently no Pkcs1v2Decrypt(), this is also a newly implemented API but the converse of Pkcs1v2Encypt().  Pkcs1v2Encrypt() (existing) and Pkcs1v2Decrypt() (new) both take they keys from DER-encoded certificates/keys.  RsaOaepEncrypt() and RsaOaepDecrypt() both take keys from RsaContext.  The internal functions use a common ENV_PKEY.

More from the Bugzilla:

BasecryptLib currently only provides RSAES-OAEP encryption capability with Pkcs1v2Encrypt() which takes as input a DER encoded x.509 certificate.  A DXE application which needs access to RSAES-OAEP encryption and decryption capabilities currently only has the option of statically linking OpensslLib and using functions such as RSA_public_encrypt() and RSA_private_decrypt().  These applications would benefit from an expanded access to RSAES-OAEP encryption / decryption capability in BaseCryptLib so that the shared crypto driver can be used and the applciation can be migrated away from RSA_public_decrypt() and RSA_private_decrypt() which are deprecated in Openssl 3.

There is the following challenges with migrating to BaseCryptLib interfaces:

	1) BaseCryptLib Pkcs1v2Encrypt() requires the use of an X.509 DER-encoded certificate to pass the public key.  This interface is dissimilar from the rest of the RSA APIs in BasecryptLib.  Applications that have used other RSA APIs from BaseCryptLib for key generation and management such as RsaGenerateKey() and RsaSetKey() will not have such a structure available.
	2) BaseCryptLib currently exposes no decryption capability.

This feature provides an easy migration path for drivers/applications which need access to RSAES-OAEP encryption / decryption and that are currently using an RsaContext structure to pass key components to OpensslLib. These applications can be easily migrated to one of the new APIs to remove the direct dependency on OpensslLib, migrate away from deprecated interfaces, take advantage of CryptoPkg/Driver, and get BasecryptLib access to RSAES-OAEP decryption.

Key changes proposed:
InternalPkcs1v2Encrypt(): New internal-only function created from refactoring of Pkcs1v2Encrypt().  Takes key input from an ENV_PKEY and is used by both public functions Pkcs1v2Encrypt() and RsaOaepEncrypt().

Pkcs1v2Encrypt(): has been refactored to create InternalPkcs1v2Encrypt() but the public interface is maintained.

RsaOaepEncrypt(): New function takes key input from an RsaContext, creates an ENV_PKEY, and calls InternalPkcs1v2Encrypt()

InternalPkcs1v2Decrypt(): New internal-only function InternalPkcs1v2Decrypt() takes key input from an ENV_PKEY and provides the RSAES-OAEP decryption capability to Pkcs1v2Decrypt() and RsaOaepDecrypt().

Pkcs1v2Decrypt(): New public function Pkcs1v2Decrypt() takes a DER-encoded private key, creates an ENV_PKEY, and calls InternalPkcs1v2Decrypt()

RsaOaepDecrypt(): New public function RsaOaepDecrypt() takes a pointer to RsaContext, creates an ENV_PKEY, and calls InternalPkcs1v2Decrypt()

Thanks,

Chris

[You don't often get email from yi1.li@intel.com. Learn why this is important at https://aka.ms/LearnAboutSenderIdentification ]

Hi Chris,

1. Please create a feature request BugZilla to introduce the background of the new API, such as purpose and application scenarios.
2. I took a quick look, the new API will make Pkcs1v2De/Encrypt support RsaContext input and the rest is same as old API right?

Regards,
Yi

Subject: [PATCH 1/3] CryptoPkg/BaseCryptLib: add additional RSAEP-OAEP crypto functions

From: Chris Ruffin <v-chruffin@microsoft.com>

Expand the availability of the RSAEP-OAEP crypto capability in BaseCryptLib.  Applications using RSA crypto functions directly from OpensslLib can transition to BaseCryptLib to take advantage of the shared crypto feature in CryptoDxe.

Pkcs1v2Decrypt(): decryption using DER-encoded private key
RsaOaepEncrypt(): encryption using RSA contexts
RsaOaepDecrypt(): decryption using RSA contexts

Subject: RE: [PATCH 1/3] CryptoPkg/BaseCryptLib: add additional RSAEP-OAEP crypto functions


Hi Yi, thanks for  your email.  I created a Bugzilla ticket for this, see Bugzilla ID #4732: https://bugzilla.tianocore.org/show_bug.cgi?id=4732.  The Pkcs1v2Encrypt() API is maintained but the implementation is refactored.  There is currently no Pkcs1v2Decrypt(), this is also a newly implemented API but the converse of Pkcs1v2Encypt().  Pkcs1v2Encrypt() (existing) and Pkcs1v2Decrypt() (new) both take they keys from DER-encoded certificates/keys.  RsaOaepEncrypt() and RsaOaepDecrypt() both take keys from RsaContext.  The internal functions use a common ENV_PKEY.

More from the Bugzilla:

BasecryptLib currently only provides RSAES-OAEP encryption capability with Pkcs1v2Encrypt() which takes as input a DER encoded x.509 certificate.  A DXE application which needs access to RSAES-OAEP encryption and decryption capabilities currently only has the option of statically linking OpensslLib and using functions such as RSA_public_encrypt() and RSA_private_decrypt().  These applications would benefit from an expanded access to RSAES-OAEP encryption / decryption capability in BaseCryptLib so that the shared crypto driver can be used and the applciation can be migrated away from RSA_public_decrypt() and RSA_private_decrypt() which are deprecated in Openssl 3.

There is the following challenges with migrating to BaseCryptLib interfaces:

	1) BaseCryptLib Pkcs1v2Encrypt() requires the use of an X.509 DER-encoded certificate to pass the public key.  This interface is dissimilar from the rest of the RSA APIs in BasecryptLib.  Applications that have used other RSA APIs from BaseCryptLib for key generation and management such as RsaGenerateKey() and RsaSetKey() will not have such a structure available.
	2) BaseCryptLib currently exposes no decryption capability.

This feature provides an easy migration path for drivers/applications which need access to RSAES-OAEP encryption / decryption and that are currently using an RsaContext structure to pass key components to OpensslLib. These applications can be easily migrated to one of the new APIs to remove the direct dependency on OpensslLib, migrate away from deprecated interfaces, take advantage of CryptoPkg/Driver, and get BasecryptLib access to RSAES-OAEP decryption.

Key changes proposed:
InternalPkcs1v2Encrypt(): New internal-only function created from refactoring of Pkcs1v2Encrypt().  Takes key input from an ENV_PKEY and is used by both public functions Pkcs1v2Encrypt() and RsaOaepEncrypt().

Pkcs1v2Encrypt(): has been refactored to create InternalPkcs1v2Encrypt() but the public interface is maintained.

RsaOaepEncrypt(): New function takes key input from an RsaContext, creates an ENV_PKEY, and calls InternalPkcs1v2Encrypt()

InternalPkcs1v2Decrypt(): New internal-only function InternalPkcs1v2Decrypt() takes key input from an ENV_PKEY and provides the RSAES-OAEP decryption capability to Pkcs1v2Decrypt() and RsaOaepDecrypt().

Pkcs1v2Decrypt(): New public function Pkcs1v2Decrypt() takes a DER-encoded private key, creates an ENV_PKEY, and calls InternalPkcs1v2Decrypt()

RsaOaepDecrypt(): New public function RsaOaepDecrypt() takes a pointer to RsaContext, creates an ENV_PKEY, and calls InternalPkcs1v2Decrypt()

Thanks,

Chris

[You don't often get email from yi1.li@intel.com. Learn why this is important at https://aka.ms/LearnAboutSenderIdentification ]

Hi Chris,

1. Please create a feature request BugZilla to introduce the background of the new API, such as purpose and application scenarios.
2. I took a quick look, the new API will make Pkcs1v2De/Encrypt support RsaContext input and the rest is same as old API right?

Regards,
Yi

Subject: [PATCH 1/3] CryptoPkg/BaseCryptLib: add additional RSAEP-OAEP crypto functions

From: Chris Ruffin <v-chruffin@microsoft.com>

Expand the availability of the RSAEP-OAEP crypto capability in BaseCryptLib.  Applications using RSA crypto functions directly from OpensslLib can transition to BaseCryptLib to take advantage of the shared crypto feature in CryptoDxe.

Pkcs1v2Decrypt(): decryption using DER-encoded private key
RsaOaepEncrypt(): encryption using RSA contexts
RsaOaepDecrypt(): decryption using RSA contexts

[edk2-devel] [PATCH v2 0/3] CryptoPkg/BaseCryptLib: add additional RSAES-OAEP crypto functions

[Chris Ruffin via groups.io]

From: Chris Ruffin <v-chruffin@microsoft.com>

v2 patchset adds:
- Add digest length parameter to RsaOaepEncrypt(), RsaOaepDecrypt() so that
SHA256, SHA384, SHA512 message digests and mask generation functions can
be used with the API.
- Add NullLib implementation for BaseCryptLibMbedTls
- Cleanups from v1 review
- Significantly refactored and expanded test suite:
  - Use UNIT_TEST_CONTEXT and abstaction to run same tests on
    Pkcs1v2Encrypt()/Pkcs1v2Decrypt() and RsaOaepEncrypt() RsaOaepDecrypt()
  - Align DER Certificate / PrivateKey used with Pkcs1v2 APIs
    with RsaN, RsaE, RsaD parameters used by RsaOaep APIs
    so that they represent the same keys.
  - Implement fixed ciphertext test for Pkcs1v2Decrypt(), RsaOaepDecrypt()
  - Implementation was also checked with wycheproof test vectors (not
    included in the patch).

  CryptoPkg/BaseCryptLib: add additional RSAES-OAEP crypto functions
  CryptoPkg/Driver: add additional RSAES-OAEP crypto functions
  CryptoPkg/BaseCryptLibUnitTest: add unit test functions

[edk2-devel] [PATCH v2 1/3] CryptoPkg/BaseCryptLib: add additional RSAES-OAEP crypto functions

[Chris Ruffin via groups.io]

From: Chris Ruffin <v-chruffin@microsoft.com>

Expand the availability of the RSAES-OAEP crypto capability in
BaseCryptLib.  Applications using RSA crypto functions directly from
OpensslLib can transition to BaseCryptLib to take advantage of the
shared crypto feature in CryptoDxe.

Pkcs1v2Decrypt(): decryption using DER-encoded private key
RsaOaepEncrypt(): encryption using RSA contexts
RsaOaepDecrypt(): decryption using RSA contexts

Fixes: https://bugzilla.tianocore.org/show_bug.cgi?id=4732
Gihub PR: https://github.com/tianocore/edk2/pull/5473

Re: [edk2-devel] [PATCH v2 0/3] CryptoPkg/BaseCryptLib: add additional RSAES-OAEP crypto functions

[Li, Yi]

Appreciate your efforts in optimization of unit test, for this patch set:

Looks good to me.

Subject: [edk2-devel] [PATCH v2 0/3] CryptoPkg/BaseCryptLib: add additional RSAES-OAEP crypto functions

From: Chris Ruffin <v-chruffin@microsoft.com>

v2 patchset adds:
- Add digest length parameter to RsaOaepEncrypt(), RsaOaepDecrypt() so that SHA256, SHA384, SHA512 message digests and mask generation functions can be used with the API.
- Add NullLib implementation for BaseCryptLibMbedTls
- Cleanups from v1 review
- Significantly refactored and expanded test suite:
  - Use UNIT_TEST_CONTEXT and abstaction to run same tests on
    Pkcs1v2Encrypt()/Pkcs1v2Decrypt() and RsaOaepEncrypt() RsaOaepDecrypt()
  - Align DER Certificate / PrivateKey used with Pkcs1v2 APIs
    with RsaN, RsaE, RsaD parameters used by RsaOaep APIs
    so that they represent the same keys.
  - Implement fixed ciphertext test for Pkcs1v2Decrypt(), RsaOaepDecrypt()
  - Implementation was also checked with wycheproof test vectors (not
    included in the patch).
