new_cipher

fn new_cipher(key []u8) cipher.Block

new_cipher creates and returns a new [AesCipher]. The key argument should be the AES key, either 16, 24, or 32 bytes to select AES-128, AES-192, or AES-256.

AesCipher

free

fn (mut c AesCipher) free()

free the resources taken by the AesCipher c

[Return to contents]

block_size

fn (c &AesCipher) block_size() int

block_size returns the block size of the checksum in bytes.

[Return to contents]

encrypt

fn (c &AesCipher) encrypt(mut dst []u8, src []u8)

encrypt encrypts the first block of data in src to dst.

Note: dst and src are both mutable for performance reasons.

Note: dst and src must both be pre-allocated to the correct length.

Note: dst and src may be the same (overlapping entirely).

[Return to contents]

decrypt

fn (c &AesCipher) decrypt(mut dst []u8, src []u8)

decrypt decrypts the first block of data in src to dst.

Note: dst and src are both mutable for performance reasons.

Note: dst and src must both be pre-allocated to the correct length.

Note: dst and src may be the same (overlapping entirely).
