The problem is that I'm pretty sure that storing together, the salt, the digest of the passphrase - which is at the end the symmetric key used to encrypt the private key - and the private key itself, encrypted with the digest of the passphrase, is a naive solution. Storing the digest of course negates both the PKBDF function and the ... irina rachmaninoff

Web18. Well, one reason to hash the data before signing it is because RSA can handle only so much data; we might want to sign messages longer than that. For example, suppose we are using a 2k RSA key; that means that the RSA operation can handle messages up to 2047 bits; or 255 bytes. We often want to sign messages longer than 255 bytes.
