Detailed Description
An abstract base class for message digests.
Constructor & Destructor Documentation
◆ ~Digest()
|
virtual |
Destructor.
Member Function Documentation
◆ finish()
|
pure virtual |
Finish generating the digest.
- Parameters
-
digest The array into which to store the digest. This array must be at least the length returned by size().
Implemented in MD5Digest, and SHA1Digest.
◆ reset()
|
pure virtual |
Reset the object for a new digest.
Implemented in MD5Digest, and SHA1Digest.
◆ size()
|
pure virtual |
Return the size of the digest generated by this class, in bytes.
Implemented in MD5Digest, and SHA1Digest.
◆ update()
|
pure virtual |
Update the digest with more data.
- Parameters
-
buf A pointer to the data. len The length of the data.
- Exceptions
-
IOException If the maximum length of data that this class can compute a digest for would be exceeded by this call.
Implemented in MD5Digest, and SHA1Digest.
