Constructor Detail

SHA384Digest

public SHA384Digest()
Standard constructor

SHA384Digest

public SHA384Digest(SHA384Digest t)
Copy constructor. This will copy the state of the provided message digest.
Method Detail

getAlgorithmName

public java.lang.String getAlgorithmName()
Description copied from interface: Digest
return the algorithm name
Following copied from interface: org.bouncycastle.crypto.Digest
Returns:
the algorithm name

getDigestSize

public int getDigestSize()
Description copied from interface: Digest
return the size, in bytes, of the digest produced by this message digest.
Following copied from interface: org.bouncycastle.crypto.Digest
Returns:
the size, in bytes, of the digest produced by this message digest.

doFinal

public int doFinal(byte[] out,
                   int outOff)
Description copied from interface: Digest
close the digest, producing the final digest value. The doFinal call leaves the digest reset.
Following copied from interface: org.bouncycastle.crypto.Digest
Parameters:
out - the array the digest is to be copied into.
outOff - the offset into the out array the digest is to start at.

reset

public void reset()
reset the chaining variables
Overrides:
reset in class LongDigest
