Unfortunately this is not how it works. The ncr-setkey sets the master key which is used to encrypt/decrypt keys that are stored in the filesystem. The aes and rsa examples demonstrate how to generate and store keys. There is no documentation, but a high level description can be found at: https://www.cosic.esat.kuleuven.be/publications/article-2001.pdf regards, Nikos _______________________________________________ Cryptodev-linux-devel mailing list Cryptodev-linux-devel@gna.org https://mail.gna.org/listinfo/cryptodev-linux-devel
