Module Netsys_crypto_modes.Symmetric_cipher

module Symmetric_cipher: sig .. end

Access symmetric ciphers

type sc_ctx = {

	`set_iv : string -> unit;`
	`set_header : string -> unit;`
	`encrypt : Netsys_types.memory -> Netsys_types.memory -> unit;`

}

type sc = {

val extract : (module Netsys_crypto_types.SYMMETRIC_CRYPTO) ->
       string * string -> sc

extract scrypto (name,mode): returns the cipher called name in mode as scipher, or raises Not_found

val extract_all : (module Netsys_crypto_types.SYMMETRIC_CRYPTO) ->
       sc list

Extracts all ciphers

val cbc_of_ecb : sc ->
       sc

For a given cipher in ECB mode, a new cipher in CBC mode is returned. Raises Not_found if the input is not in ECB mode.

val ofb_of_ecb : sc ->
       sc

For a given cipher in ECB mode, a new cipher in OFB mode is returned. Raises Not_found if the input is not in ECB mode.

val ctr_of_ecb : sc ->
       sc

For a given cipher in ECB mode, a new cipher in CTR mode is returned. Raises Not_found if the input is not in ECB mode.
