sha Hash 
MessageDigest digest = MessageDigest.getInstance("SHA1");
digest.update(source.getBytes(), 0, source.length());

Stringsha1Hash(String text)
Compute the SHA-1 hash of a string, and return it has a string of hexadecimal numbers. 
return bytesToHex(computeHash(text, HASH_SHA1));
Stringsha1Hash(String toHash)
sha Hash 
byte[] uniqueKey = toHash.getBytes();

...
Stringsha1Hash(String tohash)
sha Hash 
byte[] b = tohash.getBytes("UTF-8");
MessageDigest sha1 = MessageDigest.getInstance("SHA");
b = sha1.digest(b);
return byteToHex(b);
Stringsha1HashHex(String data)
sha Hash Hex 
return sha1HashHex(data.getBytes());
intsha1HashInt(String text)
Compute the SHA-1 hash of a string, and return a truncated int-value of the hash. 
return truncateHashToInt(computeHash(text, HASH_SHA1));
Stringsha1Hex(byte[] bytes)
sha Hex 
return toHex(sha1(bytes));
Stringsha1Hex(String data)
sha Hex
