Constructor & Destructor Documentation

SHA1Digest()

SHA1Digest

(

)

Construct a new SHA1Digest.

~SHA1Digest()

~SHA1Digest ( )

virtual

Destructor.

Member Function Documentation

finish()

void finish ( byte_t *  digest )

virtual

Finish generating the digest.

Parameters

digest

The array into which to store the digest. This array must be at least the length returned by size().

Implements Digest.

reset()

void reset ( )

virtual

Reset the object for a new digest.

Implements Digest.

size()

virtual size_t size ( ) const

inlinevirtual

Return the size of the digest generated by this class, in bytes.

Implements Digest.

update()

void update ( const byte_t *  buf, size_t  len  )

virtual

Update the digest with more data.

Parameters

buf	A pointer to the data.
len	The length of the data.

Exceptions

IOException

If the maximum length of data that this class can compute a digest for would be exceeded by this call.

Implements Digest.
