Class StringDigestUtil

java.lang.Object

org.eclipse.aether.util.StringDigestUtil

public final class StringDigestUtil
extends java.lang.Object

A simple digester utility for Strings. Uses MessageDigest for requested algorithm. Supports one-pass or several rounds of updates, and as result emits hex encoded String.

Since:

1.9.0

Constructs instance with given algorithm.

Method Detail

update

public StringDigestUtil update(java.lang.String data)

Updates instance with passed in string.

digest

public java.lang.String digest()

Returns the digest of all strings passed via update(String) as hex string. There is no state preserved and due implementation of MessageDigest.digest(), same applies here: this instance "resets" itself. Hence, the digest hex encoded string is returned only once.

MessageDigest.digest()

sha1

public static StringDigestUtil sha1()

Helper method to create StringDigestUtil using SHA-1 digest algorithm.

sha1

public static java.lang.String sha1(java.lang.String string)

Helper method to calculate SHA-1 digest and hex encode it.
