No. Litecoin uses an algorithm called scrypt which has variables that determine the amount of CPU/RAM required to compute hash. Litecoin's scrypt parameters are fixed at N = 1024; p = 1; r = 1. (http://cryptocur.com/litecoin/) Users of Scypt for password hashing purposes should have the parameters set much, much higher which will put password cracking out ...
The unstated context of this question is an SSH server: these are negotiable cryptographic options in the SSH transport protocol. You may want to update the question to indicate this. From the form of your question, I first want to clear up something. When you ask: Is it ok to use diffie-hellman-group14-sha1 along with hmac-sha2-256. Would ...
Your approach is sound (even if we should always remember the first law of cryptography: "don't roll your own"). If I may suggest some slight twists: Compute the SHA256 checksum of some fixed salt (better if depending on the file system, e.g. a random sequence stored therein) and the user password. This prevents an attacker from having a database of SHA256 ...
I got a lead with XEX. PS: Please feel free to share any better answers or insights, and I will select yours as final instead.
