Tested this and it’s compatible with Perl’s Digest::MD5: StringBuilder hexString = new StringBuilder(); byte[] bytes = digester.digest(); for (int i=0;i < bytes.length; i++) { hexString.append(Integer.toHexString((bytes[i] >>> 4) & 0×0F)); hexString.append(Integer.toHexString(0×0F & bytes[i])); } // hexString.toString() will give you your hex string!
