Method Detail

encodePwd

public byte[] encodePwd(String pwd)

Returns the hash value of the string using "SHA-1" algorithm

Parameters:

pwd - the string to be hashed

Returns:

the byte array containing the hash value of the password NOTE: This method currently uses UTF-16 as charset to encode the password, this might be supposed to change

matchPwd

public boolean matchPwd(String encoded,
                        String plain)

Hashes the given plain text using "SHA-1 " and compares it to the given encoded value

Parameters:

encoded - the string representation of the encoded byte array (should be UTF-16)

the - plain text to be compared

Returns:

true both the values are same, else returns false NOTE: It is supposed that these encoded bytes are in UTF-16 format. IF not they are to be converted to UTF-16 before making a string out of it.

testEncoding

public static void testEncoding(String encStr)
                         throws UnsupportedEncodingException

Throws:

UnsupportedEncodingException

main

public static void main(String[] args)
