Function Documentation

ct_sha1()

constexpr std::array<unsigned char, 20> ct_sha1 ( const unsigned char(&)  in[N] )

constexpr

Calculates the SHA-1 digest in compile-time if the arguments are constexpr.

Template Parameters

HasTrailingZero	Whether the input data is a null terminated string
N	The length of the input data array.

Parameters

in	The input data to hash.

Returns

The 20 bytes representing a Sha1 digest of the input data.

sha1Done()

constexpr Sha1Status Detail::sha1Done ( Sha1State &  md, unsigned char *const  out  )

constexpr

Terminate the hash to get the digest

Parameters

md	The hash state
out	[out] The destination of the hash (20 bytes)

Returns

Sha1Status::Ok if successful

sha1Process()

constexpr Sha1Status Detail::sha1Process ( Sha1State &  md, const unsigned char(&)  in[N]  )

constexpr

Process a block of memory though the hash

Template Parameters

HasTrailingZero	Whether the input data is a null terminated string
N	The length of the input data array.

Parameters

md	The hash state
in	The data to hash

Returns

Sha1Status::Ok if successful
