Member Function Documentation

final() [1/2]

MD5::MD5Result MD5::final

(

)

Finishes off the hash, and returns the 16-byte hash data.

Definition at line 264 of file MD5.cpp.

final() [2/2]

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()

MD5::MD5Result MD5::hash ( ArrayRef< uint8_t >  Data )

static

Computes the hash for a given bytes.

Definition at line 291 of file MD5.cpp.

References llvm::Data, final(), and update().

result()

MD5::MD5Result MD5::result

(

)

Finishes off the hash, and returns the 16-byte hash data.

This is suitable for getting the MD5 at any time without invalidating the internal state, so that more calls can be made into update.

Definition at line 270 of file MD5.cpp.

stringifyResult()

void MD5::stringifyResult ( MD5Result &  Result, SmallVectorImpl< char > &  Str  )

static

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

The result will be of length 32.

Definition at line 287 of file MD5.cpp.

Referenced by computeHashString(), llvm::getUniqueInternalLinkagePostfix(), and llvm::getUniqueModuleId().

update() [1/2]

void MD5::update

(

ArrayRef< uint8_t >

Data

)

Updates the hash for the byte stream provided.

Incrementally add the bytes in Data to the hash.

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.
