类 CommonSha1Utils

java.lang.Object

com.qcloud.cos.common_utils.CommonSha1Utils

public final class CommonSha1Utils
extends Object

求sha1, 未使用JAVA自带类，是为了获取分片的中间状态(state数组)

方法详细资料

update

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

Add specific bytes to the digest.

update

public void update(byte[] input)

Add an array of bytes to the digest.

updateASCII

public void updateASCII(String input)

Treat the string as a sequence of ISO-Latin1 (8 bit) characters.

init

public void init()

SHA1Init - Initialize new context

update

public void update(byte b)

Add one byte to the digest. When this is implemented all of the abstract class methods end up calling this method for types other than bytes.

finish

public void finish()

Complete processing on the message digest.

getAlg

public String getAlg()

Return a string that identifies this algorithm

digout

public String digout()

Print out the digest in a form that can be easily compared to the test vectors.

dumpTempState

public String dumpTempState()
