Re: [Cryptix-users] Unsupported keysize or algorithm parameters

[Eric B. <Eri...@We...>]

This is a similiar issue I was running into using the JCE RC4 =
encryption.  The only way I could get the code below to work was using a =
maximum of 16 characters as the key, which is pretty weak.  I couldn't =
find and policy files and such.
=20
All I am trying to do is RC4 encrypt a string using another string that =
is 128 characters long as the string, and I am failing miserably.
=20
                 java.security.Security.addProvider(new =
cryptix.jce.provider.CryptixCrypto());
                 RawSecretKey v_key =3D new RawSecretKey("RC4", =
"GFgksgjGNDKGlsgnLDGGknhjLdgnLSgnlsdkgNLSkgnlesnvlKENVlkENVLkNELVknLEKVns=
ev".getBytes());
                 alg =3D Cipher.getInstance("RC4","CryptixCrypto");
                 alg.init(Cipher.ENCRYPT_MODE, v_key );
                 byte[] v_encrypted  =3D alg.doFinal( =
v_form_parameter.getBytes() );

Hi Rakesh,

did you install the 'unlimited strength' policy files ?

Greetings
