APU_DECLARE()

APU_DECLARE

(

void

)

Computes SipHash-2-4, producing a 64bit (APR_SIPHASH_DSIZE) hash from a message and a 128bit (APR_SIPHASH_KSIZE) secret key, into a possibly unaligned buffer (using the little endian representation as defined by the authors for interoperabilty) usable as a MAC.

Return APR-util's version information information in a numeric form.

Parameters

pvsn	Pointer to a version structure for returning the version information.

Computes SipHash-4-8, producing a 64bit (APR_SIPHASH_DSIZE) hash from a message and a 128bit (APR_SIPHASH_KSIZE) secret key, into a possibly unaligned buffer (using the little endian representation as defined by the authors for interoperabilty) usable as a MAC.

Initialize the SHA digest

Parameters

context

The SHA context to initialize

Update the SHA digest

Parameters

context	The SHA1 context to update
input	The buffer to add to the SHA digest
inputLen	The length of the input buffer

Update the SHA digest with binary data

Parameters

context	The SHA1 context to update
input	The buffer to add to the SHA digest
inputLen	The length of the input buffer

Finish computing the SHA digest

Parameters

digest	the output buffer in which to store the digest
context	The context to finalize
out	The output buffer (or MAC)
src	The message
len	The length of the message
key	The secret key

Returns

The hash value as a 64bit unsigned integer
