Hello, I just released a program to be used with the Cyberflex Access card (and Cryptoflex 8K card if someone can figure out how to order the key binary on the card - the code is included) This program allows you to encrypt files on your Unix machine using your smartcard. It works like this: ./cscrypt src dest The src is the file to encrypt. It will create an IDEA 128 bit key and encrypt the file with it in 16 byte blocks. Then it will create a new file dest with the following format: [cipher type] [file size] [key size] [encrypted IDEA key] [RFU] [cipher text] [possibly hash checksum in the future] The IDEA key is encrypted with your RSA public key that is created when you do a csgenkey which is the same program used in the PAM module. To decrypt the file you will need your smartcard and it will read the header information off the file - decrypt the IDEA key and decrypt the file with ./csdecrypt src dest The code doesn't check for many errors but I wanted to get it out for people to play with. You should be able to use this code with many of the readers supported by PC/SC but like Jim Rees mentioned in previous posts you have to change the atr on the access card so that it has an acceptable WWT. I have tested it with the Reflex 62 reader and Todos.
