AESencrypt4x4

void AESencrypt4x4( char far * expandedkey, char far * plain, char far * crypt );

Description

Encrypts a block of data using an implementation of the Rijndael AES cipher with 128-bit key and block size. The block of data may be overwritten by the encrypted block of data.

Parameters

expandedkey

A set of round keys (generated by AESexpandKey4()) from a 16-byte (128 bit) key.

Total of 176 bytes (44 longwords)

Note: when using an AESstreamState structure (e.g., "state") then call this function using:

AESencrypt4x4(state->expanded_key, plain, crypt);

plain

A block of 16 bytes of data to be encrypted; "crypt" and "plain" may point to the same place.

crypt

A block of 16 bytes of resulting encrypted data; "crypt" and "plain" may point to the same place.

Return value

None.

Library

AES_CORE.LIB
