构造器详细资料

_SHA512tDigest

public _SHA512tDigest(int bitLength)

Standard constructor

_SHA512tDigest

public _SHA512tDigest(_SHA512tDigest t)

Copy constructor. This will copy the state of the provided message digest.

_SHA512tDigest

public _SHA512tDigest(byte[] encodedState)

方法详细资料

getAlgorithmName

public String getAlgorithmName()

从接口复制的说明: Digest

return the algorithm name

返回:

the algorithm name

getDigestSize

public int getDigestSize()

从接口复制的说明: Digest

return the size, in bytes, of the digest produced by this message digest.

返回:

the size, in bytes, of the digest produced by this message digest.

doFinal

public int doFinal(byte[] out,
                   int outOff)

从接口复制的说明: Digest

close the digest, producing the final digest value. The doFinal call leaves the digest reset.

参数:

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

指定者:

reset 在接口中 Digest

覆盖:

reset 在类中 _AbstractLongDigest

copy

public Memoable copy()

从接口复制的说明: Memoable

Produce a copy of this object with its configuration and in its current state.

The returned object may be used simply to store the state, or may be used as a similar object starting from the copied state.

reset

public void reset(Memoable other)

从接口复制的说明: Memoable

Restore a copied object state into this object.

Implementations of this method should try to avoid or minimise memory allocation to perform the reset.

参数:

other - an object originally copied from an object of the same type as this instance.

getEncodedState

public byte[] getEncodedState()
