Java calculate hex representation of a SHA-1 digest of a String
Solution 1:
Using apache common codec library:
DigestUtils.sha1Hex("aff")
The result is 0c05aa56405c447e6678b7f3127febde5c3a9238
That's it :)
Solution 2:
This is happening because cript.digest() returns a byte array, which you're trying to print out as a character String. You want to convert it to a printable Hex String.
Easy solution: Use Apache's commons-codec library:
String password = new String(Hex.encodeHex(cript.digest()),
CharSet.forName("UTF-8"));
