Returns a hash function implementing the SHA-1 algorithm (160 hash bits) by delegating to the SHA-1 MessageDigest .

Usage

From source file:org.dcache.gridsite.ServletDelegation.java

private String generateDelegationId() throws DelegationException {
    String generator = getClientDn() + getFqanList();
    byte[] raw = generator.getBytes(Charsets.UTF_8);
    byte[] digest = Hashing.sha1().hashBytes(raw).asBytes();
    return BaseEncoding.base16().encode(digest, 0, 20);
}
