AES algorithm implementation by ABAP

ABAP Utilities for AES encryption, decryption under MIT License.

Actual Implementation is done by the more generic Rijndael way, and AES is treated as a special case.

Supporting:

  • Encryption mode: ECB, CBC, PCBC, CFB, OFB, CTR.
  • Padding standard: None, PKCS #5, PKCS #7. (Please use PKCS #7, No Padding and PKCS #5 do not work well with AES, unless you know clearly what they are doing.)

Please just copy the source code file into ABAP editor (Source Code-Based mode), and activate it. Or install via abapGit.

Classes:

  • ZIF_AES_MODE: Interface for different encryption mode.
  • ZCL_AES_MODE_CBC: CBC mode.
  • ZCL_AES_MODE_CFB: CFB mode.
  • ZCL_AES_MODE_CTR: CTR mode.
  • ZCL_AES_MODE_ECB: ECB mode.
  • ZCL_AES_MODE_OFB: OFB mode.
  • ZCL_AES_MODE_PCBC: PCBC mode.
  • ZCL_BYTE_PADDING_UTILITY: Abstract class for Byte padding utilities, including factory method to get concrete class instances.
  • ZCL_PADDING_UTILITY_NONE: No padding.
  • ZCL_PADDING_UTILITY_PKCS_5: Padding using PKCS #5.
  • ZCL_PADDING_UTILITY_PKCS_7: Padding using PKCS #7.
  • ZCL_RIJNDAEL_UTILITY: implementation of Rijndael, encrypt and decrypt using xstring.
  • ZCL_AES_UTILITY: AES wrapper on ZCL_RIJNDAEL_UTILITY, just need to provide key and data.
  • ZCL_AES_UTILITY_TEST:
