Block cipher engine constructor.

Return the block size of the block cipher.

Decrypt data encrypted using the encrypt function.

The input, key and iv parameters should be of any type that can be coerced to byte array.

Encrypt arbitrary length data using one of the supported encryption scheme. The default encryption scheme is: :aes128-cbc-hmac-sha256.

Example: (encrypt "hello world" mykey myiv)

You can specify an other encryption scheme passing an additional parameter.

Example: (encrypt "hello world" mykey myiv {:alg :aes128-cbc-hmac-sha512})

See the documentation for know the complete list of supported encryption schemes.

The input, key and iv parameters should be of any type that can be coerced to byte array.

End the encryption process. This is only usefull for aead block ciphers, for the rest it always return 0 and does nothing.

A backward compatibility alias for output-size function.

A backward compatibility alias for output-size function.

Initialize the cipher engine.

A backward compatibility alias for init!

Get the output size of the aead block cipher.

Encrypt or decrypt a bytes using the specified engine. The length of the block to encrypt or decrypt depends on the used crypto engine.

Encrypt or decrypt a bytes using the specified engine. Is a specialized version of process-block! for stream ciphers and aead ciphers.

Split a byte array in blocksize blocks.

Given a arbitrary size bytearray and block size in bytes, returns a vector of bytearray blocks of blocksize size. If last block does not have enought data for fill all block, it is padded using zerobyte padding.
