Member Function Documentation

◆ final()

void MD5::final ( MD5Result & Result )

Finishes off the hash and puts the result in result.

Finish the hash and place the resulting hash into result.

Parameters

Result is assumed to be a minimum of 16-bytes in size.

◆ hash()

std::array< uint8_t, 16 > MD5::hash ( ArrayRef< uint8_t > Data )

static

Computes the hash for a given bytes.

◆ stringifyResult()

void MD5::stringifyResult	(	MD5Result &	Result,
		SmallString< 32 > &	Str
	)

static

Translates the bytes in Res to a hex string that is deposited into Str.

The result will be of length 32.

◆ update() [2/2]

void MD5::update ( StringRef Str )

Updates the hash for the StringRef provided.

Add the bytes in the StringRef Str to the hash.
