Sumu-Ning/AES

AES and Rijndael encryption and decryption utilities for ABAP, covering six cipher modes and three padding schemes, installed by copying the source or through abapGit.

AES implements AES encryption and decryption in ABAP as a special case of the more general Rijndael cipher, through classes such as ZCL_AES_UTILITY and ZCL_RIJNDAEL_UTILITY. It covers six modes, ECB, CBC, PCBC, CFB, OFB and CTR, and three padding schemes, and the README says PKCS #5 and no padding do not work well with AES unless you know exactly what they do, recommending PKCS #7 instead. Installation is a source file copied straight into the ABAP editor, or pulled in through abapGit.

Encryption and signingABAPEncryption and signingcapabilityEncrypting, decrypting and signing data from application code: a document wrapped for one recipient, a payload signed so its origin can be checked, a value enciphered with a key both sides hold. Encryption of a connection, TLS, is set up in the system and is outside this concern.

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:
