New authentication methods in OraSFTP

OraSFTP version 1.4.5 adds support for Elliptic Curve based SFTP key exchange and public-key signatures. The complete list of new cryptography enhancements in this version is available below:

Key exchange (KEX)

An SSH session begins with a cryptographic exchange based on asymmetric cryptography algorithms, in order for the client and the server to agree on a shared session key material that will be used to secure and encrypt the data exchanged in a session. The new algorithms supported by OraSFTP as of version 1.4.5 are:

[+] diffie-hellman-group15-sha384
[+] diffie-hellman-group16-sha512
[+] diffie-hellman-group17-sha512
[+] diffie-hellman-group18-sha512
[+] ecdh-sha2-nistp256
[+] ecdh-sha2-nistp384
[+] ecdh-sha2-nistp521
[+] ecdh-sha2-secp256k1

Signatures

Public key signatures are used in SSH sessions for server and client authentication. Client and server authentication takes place at separate times and uses different public keys. The new algorithms supported by OraSFTP as of version 1.4.5 are:

[+] ecdsa-sha2-nistp256
[+] ecdsa-sha2-nistp384
[+] ecdsa-sha2-nistp521
[+] ecsa-sha2-secp256k1
