goog.crypt.Ctr

Provided By	`goog.crypt.Ctr`

Implementation of Ctr mode for block ciphers. See http://en.wikipedia.org/wiki/Block_cipher_modes_of_operation #Cipher-block_chaining_.28Ctr.29. for an overview, and http://csrc.nist.gov/publications/nistpubs/800-38a/sp800-38a.pdf for the spec.

new Ctr( `cipher` )

Parameters

`cipher`	`goog.crypt.BlockCipher`
	The block cipher to use.

VIEW SOURCE

Instance Methods

Decrypts a message. In CTR, this is the same as encrypting.

Parameters

`cipherText`	`(Array<number>\|Uint8Array)`
	Message to decrypt. The length does not have to be a multiple of the blocksize.
`initialVector`	`(Array<number>\|Uint8Array)`
	Initial vector for the Ctr mode. An array of bytes with the same length as the block size.

Returns

Array<number>

Decrypted message.

VIEW SOURCE

Encrypts a message.

Parameters

`plainText`	`(Array<number>\|Uint8Array)`
	Message to encrypt. An array of bytes. The length does not have to be a multiple of the blocksize.
`initialVector`	`(Array<number>\|Uint8Array)`
	Initial vector for the Ctr mode. An array of bytes with the same length as the block size, that should be not reused when using the same key.

Returns

Array<number>

Encrypted message.
