Detailed Description

The sha256 class provides a simple sha256 implementation.

Constructor & Destructor Documentation

sha256()

sha256::sha256

(

)

Creates an instance of the sha256 class.

~sha256()

virtual sha256::~sha256 ( )

virtual

Deletes this instance of the sha256 class.

Member Function Documentation

append()

bool sha256::append ( const byte_t *  data, uint32_t  size  )

virtual

Appends "size" bytes of "data" to the data to be hashed. Returns true on success or false if an error occurred.

Reimplemented from hash.

clear()

bool sha256::clear ( )

virtual

Clears the current hash and any data that had previously been appended. Returns true on success or false if an error occurred.

Reimplemented from hash.

getError()

hasherror_t sha256::getError ( )

virtual

Returns the most recent error.

Reimplemented from hash.

getHash()

const byte_t* sha256::getHash ( )

virtual

Returns the current hash on success or NULL if an error occurred. Note that the current hash will be an empty string if no data has been appended yet.

Implements hash.

getHashSize()

uint64_t sha256::getHashSize ( )

virtual

Returns the number of bytes in the hash.

Reimplemented from hash.
