Detailed Description

Class that encapsulates SHA-1 hashing, a crypticographic-strength 160-bit hash function. It's not as fast as our other hashing methods, but has an extremely low chance of having collisions.

Constructor & Destructor Documentation

SHA1::SHA1	(	const void *	data = NULL,
		size_t	size = 0

Member Function Documentation

void SHA1::append	(	const void *	data,
		size_t	size
	)

Append more data.

void SHA1::append ( string_view  s )

inline

Append more data from a string_view.

Definition at line 580 of file hash.h.

template<class T >

void SHA1::append ( span< T >  v )

inline

Append more data from a span, without thinking about sizes.

Definition at line 585 of file hash.h.

std::string SHA1::digest

(

)

Return the digest as a hex string.

static std::string SHA1::digest ( const void *  data, size_t  size  )

inlinestatic

Roll the whole thing into one functor, return the string digest.

Definition at line 605 of file hash.h.

void SHA1::gethash

(

Hash &

h

)

Get the digest and store it in Hash h.

void SHA1::gethash ( void *  h )

inline

Get the digest and store it in h (must point to enough storage to accommodate 20 bytes).
