Detailed Description

SHA-512 hash.

Member Function Documentation

name()

virtual UString ts::SHA512::name ( ) const

overridevirtual

Algorithm name (informational only).

Returns

The algorithm name.

Implements ts::Hash.

hashSize()

virtual size_t ts::SHA512::hashSize ( ) const

overridevirtual

Size in bytes of the resulting hash.

Returns

The size in bytes of the resulting hash.

Implements ts::Hash.

blockSize()

virtual size_t ts::SHA512::blockSize ( ) const

overridevirtual

Size in bytes of the block used by the algorithm.

Returns

The size in bytes of the block used by the algorithm. Informational only. Can be zero if non significant.

Implements ts::Hash.

init()

virtual bool ts::SHA512::init ( )

overridevirtual

Reinitialize the computation of the hash.

Returns

True on success, false on error.

Implements ts::Hash.

add()

virtual bool ts::SHA512::add ( const void *  data, size_t  size  )

overridevirtual

Add some part of the message to hash.

Can be called several times.

Parameters

[in]	data	Address of message part.
[in]	size	Size in bytes of message part.

Returns

True on success, false on error.

Implements ts::Hash.

getHash()

virtual bool ts::SHA512::getHash ( void *  hash, size_t  bufsize, size_t *  retsize = nullptr  )

overridevirtual

Get the resulting hash value.

Parameters

[out]	hash	Address of returned hash buffer.
[in]	bufsize	Size in bytes of hash buffer.
[out]	retsize	Address of an integer receiving the actual returned hash size. Can be a null pointer (ignored).

Returns

True on success, false on error.

Implements ts::Hash.

hash() [1/2]

bool ts::Hash::hash ( const void *  data, size_t  data_size, void *  hash, size_t  hash_maxsize, size_t *  hash_retsize = nullptr  )

inherited

Compute a hash in one operation.

Same in init() + add() + getHash().

Parameters

[in]	data	Address of message to hash.
[in]	data_size	Size in bytes of message to hash.
[out]	hash	Address of returned hash buffer.
[in]	hash_maxsize	Size in bytes of hash buffer.
[out]	hash_retsize	Address of an integer receiving the actual returned hash size. Can be a null pointer (ignored).

Returns

True on success, false on error.

hash() [2/2]

bool ts::Hash::hash ( const void *  data, size_t  data_size, ByteBlock &  hash  )

inherited

Compute a hash in one operation.

Same in init() + add() + getHash().

Parameters

[in]	data	Address of message to hash.
[in]	data_size	Size in bytes of message to hash.
[out]	hash	Returned hash buffer.

Returns

True on success, false on error.
