func NewCFB8

func NewCFB8(block cipher.Block, iv []byte, decrypt bool) cipher.Stream

func NewCFB8Decrypter

func NewCFB8Decrypter(block cipher.Block, iv []byte) cipher.Stream

NewCFB8Decrypter returns a Stream which decrypts with cipher feedback mode (segment size = 8), using the given Block. The iv must be the same length as the Block's block size.

func NewCFB8Encrypter

func NewCFB8Encrypter(block cipher.Block, iv []byte) cipher.Stream

NewCFB8Encrypter returns a Stream which encrypts with cipher feedback mode (segment size = 8), using the given Block. The iv must be the same length as the Block's block size.

func NewECBDecrypter

func NewECBDecrypter(b cipher.Block) cipher.BlockMode

NewECBDecrypter returns a BlockMode which decrypts in electronic code book mode, using the given Block.

func NewECBEncrypter

func NewECBEncrypter(b cipher.Block) cipher.BlockMode

NewECBEncrypter returns a BlockMode which encrypts in electronic code book mode, using the given Block.

func NewNCFBDecrypter

func NewNCFBDecrypter(block cipher.Block, iv []byte) cipher.Stream

func NewNCFBEncrypter

func NewNCFBEncrypter(block cipher.Block, iv []byte) cipher.Stream

func NewNOFB

func NewNOFB(b cipher.Block, iv []byte) cipher.Stream

NewNOFB returns a Stream that encrypts or decrypts using the block cipher b in output feedback mode. The initialization vector iv's length must be equal to b's block size.

func NewOCFBDecrypter

func NewOCFBDecrypter(block cipher.Block, prefix []byte, resync OCFBResyncOption) cipher.Stream

NewOCFBDecrypter returns a cipher.Stream which decrypts data with OpenPGP's cipher feedback mode using the given cipher.Block. Prefix must be the first blockSize + 2 bytes of the ciphertext, where blockSize is the cipher.Block's block size. If an incorrect key is detected then nil is returned. On successful exit, blockSize+2 bytes of decrypted data are written into prefix. Resync determines if the "resynchronization step" from RFC 4880, 13.9 step 7 is performed. Different parts of OpenPGP vary on this point.

func NewOCFBEncrypter

func NewOCFBEncrypter(block cipher.Block, randData []byte, resync OCFBResyncOption) (cipher.Stream, []byte)

NewOCFBEncrypter returns a cipher.Stream which encrypts data with OpenPGP's cipher feedback mode using the given cipher.Block, and an initial amount of ciphertext. randData must be random bytes and be the same length as the cipher.Block's block size. Resync determines if the "resynchronization step" from RFC 4880, 13.9 step 7 is performed. Different parts of OpenPGP vary on this point.

func NewOFB8

func NewOFB8(b cipher.Block, iv []byte) cipher.Stream

func NewOFBNLFDecrypter

func NewOFBNLFDecrypter(newKey KeyCreator, key, iv []byte) cipher.BlockMode

func NewOFBNLFEncrypter

func NewOFBNLFEncrypter(newKey KeyCreator, key, iv []byte) cipher.BlockMode

func NewPCBCDecrypter

	OCFBResync   OCFBResyncOption = true
	OCFBNoResync OCFBResyncOption = false
)
