Converts an array of bytes into a String representing the hexadecimal values of each byte in order.

Usage

From source file:de.ks.flatadocdb.defaults.DefaultIdGenerator.java

public String getSha1Hash(Path repository, Path targetPath) {//for debugging and readability the string is used instead of the byte array. Also avoids possible programming errors using the byte array in equals/hashcode.
    String relative = getRelativePath(repository, targetPath);
    MessageDigest digest = sha1.get();
    byte[] checksum = digest.digest(relative.getBytes(Charsets.UTF_16));
    String hexString = Hex.encodeHexString(checksum);
    log.trace("Generated {} \"{}\" for {}", digest.getAlgorithm(), hexString, relative);
    return hexString;
}
