Encryption

I'm not getting a good decription of data from my server, obviously missing something.

16 byte encryption key = yaX62INZNCqJ5/6l
The unencrypted data = Test1234*
The encrypted data is:
AvbebeuvOQk5uCXqh2b+SipYJ/ISgQrzKB++6s8gHWc=

Attached PC program's ActiveX setup is attached

Any help would be terrific.
Thanks

I forgot to ad that the ActiveX padding 0 is PKCS5Padding

I have it set as DES/CBC/PKCS5Padding even though I believe I have a 16 byte key. I'm getting a padding corrupted message?

Can you post the decryption code?

I've tried it so many ways the code now looks like garbage. Off the top I'm having a problem as the PC's control says it's DES with a 16 byte key. Encryption rejects that off-hand saying DES requires an 8 byte key.

It's obviously tied up with this inconsistency with des, cbc, a bzip2 compression algorithm, rijndael, base64 encoding, sha1 hash algorithm, etc. I may have to resolve it in my web service and pass it back in a compatible format.

Any ideas would be great, I'll get it done one way or another.

Thanks
