Member Function Documentation

digest()

std::unique_ptr< xdutl::BinaryData > tenduke::crypto::libcrypto::LibCryptoMessageDigest::digest ( )

overridevirtual

Computes the digest.

Returns

data-object containing the digest

Exceptions

tenduke::crypto::CryptoException

on error

Implements tenduke::crypto::MessageDigest.

digestTo()

void tenduke::crypto::libcrypto::LibCryptoMessageDigest::digestTo ( unsigned char * messageDigest )

overridevirtual

Computes the digest to pre-allocated buffer.

Parameters

messageDigest

the computed digest is placed here (needs to proper size, use MessageDigest::length()).

Exceptions

tenduke::crypto::CryptoException

on error

Implements tenduke::crypto::MessageDigest.

length()

size_t tenduke::crypto::libcrypto::LibCryptoMessageDigest::length ( ) const

overridevirtual

Returns length (in bytes) of the resulting digest.

Returns

-

Implements tenduke::crypto::MessageDigest.

update()

xdcrypto::MessageDigest * tenduke::crypto::libcrypto::LibCryptoMessageDigest::update ( const unsigned char * message, std::size_t messageLength )

overridevirtual

Updates the digest.

Parameters

message	-
messageLength	-

Returns

this instance for chaining

Exceptions

tenduke::crypto::CryptoException

on error

Implements tenduke::crypto::MessageDigest.
