Class Sha1Hash

java.lang.Object
  org.apache.shiro.codec.CodecSupport
      org.apache.shiro.crypto.hash.AbstractHash
          org.apache.shiro.crypto.hash.Sha1Hash

All Implemented Interfaces:

Serializable, Hash

public class Sha1Hash
extends AbstractHash

Generates an SHA-1 Hash (Secure Hash Standard, NIST FIPS 180-1) from a given input source with an optional salt and hash iterations.

See the AbstractHash parent class JavaDoc for a detailed explanation of Hashing techniques and how the overloaded constructors function.
