pure virtual |
Completes the hash computation by performing final operations such as padding.
Implemented in sha1MessageDigest.
|
pure virtual |
Completes the hash computation by performing final operations such as padding.
This is equivalent to calling update() and then finalize().

|
pure virtual |
Returns the hash, as computed by the algorithm.
You must call finalize() before using this function, or the hash will not be correct. To get the size of the returned array, call getDigestLength().
- Returns
- computed hash
Implemented in sha1MessageDigest.
Referenced by messageDigest::getHexDigest().
|
pure virtual |
Returns the length of the hash.
This is the length of the array returned by getDigest().
- Returns
- length of computed hash
Implemented in sha1MessageDigest.
Referenced by messageDigest::getHexDigest().
|
virtual |
Returns the hash as an hexadecimal string.
You must call finalize() before using this function, or the hash will not be correct.
- Returns
- computed hash, in hexadecimal format
References messageDigest::getDigest(), and messageDigest::getDigestLength().
|
pure virtual |
Resets the algorithm to its initial state, so that you can compute a new hash using the same object.
Implemented in sha1MessageDigest.
|
pure virtual |
Updates the digest using the specified string.
- Parameters
-
s the string with which to update the digest.
Implemented in sha1MessageDigest.
|
pure virtual |
Updates the digest using the specified byte.
- Parameters
-
b the byte with which to update the digest.
Implemented in sha1MessageDigest.
Updates the digest using the specified array of bytes.
- Parameters
-
buffer array of bytes len number of bytes to use in the buffer
Implemented in sha1MessageDigest.
Updates the digest using the specified array of bytes, starting at the specified offset.
- Parameters
-
buffer array of bytes offset offset to start from in the array of bytes len number of bytes to use, starting at offset
Implemented in sha1MessageDigest.
