-decrypt clj multimethod

-encrypt clj multimethod

block-cipher clj

(block-cipher alg mode)

Block cipher engine constructor.

block-size clj

(block-size engine)

Return the block size of the block cipher.

decrypt clj

(decrypt input key iv)

(decrypt input
         key
         iv
         {:keys [algorithm alg] :or {alg :aes128-cbc-hmac-sha256} :as options})

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 clj

(encrypt input key iv)

(encrypt input
         key
         iv
         {:keys [algorithm alg] :or {alg :aes128-cbc-hmac-sha256} :as options})

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! clj

(end! engine output offset)

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

get-block-size clj

A backward compatibility alias for output-size function.

get-output-size clj

A backward compatibility alias for output-size function.

IBlockCipherLike clj protocol

ICipherInit clj protocol

-end clj

(-end engine out offset)

Finalize cipher engine.

-init clj

(-init engine params)

Initialize cipher engine.

init! clj

(init! engine params)

Initialize the cipher engine.

initialize! clj

A backward compatibility alias for init!

IStreamCipherLike clj protocol

output-size clj

(output-size engine length)

Get the output size of the aead block cipher.

process-block! clj

(process-block! engine in)

(process-block! engine in inoff out outoff)

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

process-bytes! clj

(process-bytes! engine in)

(process-bytes! engine in inoff out outoff)

(process-bytes! engine in inoff inlen out outoff)

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

split-by-blocksize clj

(split-by-blocksize input blocksize)

(split-by-blocksize input blocksize additional)

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.

stream-cipher clj

(stream-cipher alg)

Stream cipher engine constructor.
