hi ok as regards the key, for the test i had to do it implemented in the code and given thru a variable forget about polarssl it just another libs that i have already tested my difficulty is how to start my program for encrypt data with aes, what is the libs that i had to implement in my programm i try to understand the documentation and some sample given by mozilla the test i had to do is just to show what are the additionnal line for encrypt and decrypt data as regards the key, we have a secure network using tls, ssl and other security package, i have heard that we will try to use tpm structure and perhaps hardware for the key i don't have any more information as regards the key thanks for help me i think the lib of mozilla was great and i would like to test it regards -- dev-tech-crypto mailing list dev-tech-crypto@lists.mozilla.org https://lists.mozilla.org/listinfo/dev-tech-crypto
