The AES-P core from Alma Technologies implements the FIPS-197 Advanced Encryption Standard. It can be programmed to encrypt or decrypt 128-bit blocks of data, using 128-, 192-, or 256-bit cipher-key.

An included configurable wrapper surrounds the AES-C core and implements its fixed Block-Cipher mode of operation. This configurable wrapper supports the ECB, CBC, CFB, OFB and CTR Block-Cipher modes.
