public MD4()

メソッドの詳細

clone

public Object clone()

Returns a copy of this MD object.

オーバーライド:

clone クラス内 MessageDigest

engineReset

public void engineReset()

Resets this object disregarding any temporary data present at the time of the invocation of this call.

定義:

engineReset クラス内 MessageDigestSpi

engineUpdate

public void engineUpdate(byte b)

Continues an MD4 message digest using the input byte.

定義:

engineUpdate クラス内 MessageDigestSpi

engineUpdate

public void engineUpdate(byte[] input,
                         int offset,
                         int len)

MD4 block update operation.

Continues an MD4 message digest operation, by filling the buffer, transform(ing) data in 512-bit message block(s), updating the variables context and count, and leaving (buffering) the remaining bytes in buffer for the next update or finish.

定義:

engineUpdate クラス内 MessageDigestSpi

パラメータ:

input - input block

offset - start of meaningful bytes in input

len - count of bytes in input block to consider

engineDigest

public byte[] engineDigest()

Completes the hash computation by performing final operations such as padding. At the return of this engineDigest, the MD engine is reset.

定義:

engineDigest クラス内 MessageDigestSpi

戻り値:

the array of bytes for the resulting hash value.
