[PATCH v3 0/2] Add SM4 XTS symmetric algorithm for blk-crypto and fscrypt

Posted by Tianjia Zhang 2 years, 9 months ago

SM4 is widely used in China's data encryption software and hardware.
these algoritms are mandatory in many scenarios. This serial of
patches enables the SM4-XTS algorithm in blk-crypto and enables the
SM4-XTS/CTS algorithm in fscrypt to encrypt file content and filename.

v3 change:
  - update git commit message

v2 change:
  - As Eric said, the new FSCRYPT_MODE is defined for the unused numbers 7 and 8

Tianjia Zhang (2):
  blk-crypto: Add support for SM4-XTS blk crypto mode
  fscrypt: Add SM4 XTS/CTS symmetric algorithm support
