- 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.

```
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.
