Putty portable ssh24/18/2024 Support for ECDSA, RSA and DSA public key authentication with comprehensive user keypair management.Įncryption and security: Provides state-of-the-art encryption and security suitable as part of a standards-compliant solution meeting the requirements of PCI, HIPAA, or FIPS 140-2 validation. Support for corporation-wide single sign-on using SSPI (GSSAPI) Kerberos 5 and NTLM user authentication, as well as Kerberos 5 host authentication. ![]() ![]() State-of-the-art terminal emulation with support for the bvterm, xterm, and vt100 protocols. One of the most advanced graphical SFTP clients. Our SSH and SFTP client for Windows incorporates: Our client is free for use of all types, including in organizations. Our SSH client supports all desktop and server versions of Windows, 32-bit and 64-bit, from Windows XP SP3 and Windows Server 2003, up to the most recent – Windows 11 and Windows Server 2022.

Users of SSH however often copy the private key to other machines as well. Note that the public key format is usually more important as it is required to copy the public key to the server (which may not run the same software as the client) while the private key format can stay locally. For v2 this uses the algorithm name and base64 of the wire encoding, similar to rfc4716 format but without line breaks or PEM header/trailer. This format also varies between RSA1 (SSHv1) and RSA2 and other SSHv2 keys but less dramatically. In addition the public key is displayed in OpenSSH authorized_keys (and known_hosts) format whenever a key is generated or loaded, without explicit action. Export ssh.com key: this exports the key in the format used by the commercial SSH implementation from ssh.com, see Wikipedia, which can be imported into OpenSSH using ssh-keygen -i.Export OpenSSH key: this actually exports an Open SSL encrypted private key (PKCS#1 / PEM format), which Open SSH normally uses for RSA2 key (and OpenSSH similarly uses OpenSSL formats for DSA and ECDSA private key in v2, but in recent versions has its own format for Ed25519 private key, a new algorithm OpenSSL doesn't know about yet).Save private key: this exports the private key in proprietary/encrypted Putty format.Save public key: this exports the public key in SSH2 public key format, a standard ( RFC4716) but not widely used. ![]() There seem to be 4 options (after choosing SSH2-RSA): So yes, the SSH2-RSA indicates a RSA2 formatted key.Īlso is this key in the OpenSSH format? I see that there is a conversion tab with 2 options: export OpenSSh Key and export ssh.com key. ssh-keygen in OpenSSH calls them -t rsa1 and -t rsa (which people call rsa2 for clarity), and puttygen calls them SSH1-RSA and SSH2-RSA. OpenSSH uses two different formats (and files) for RSA keys: one for the old, weak SSHv1 protocol which you should not use (and often aren't allowed to) and one for the current SSHv2 protocol. So is SSH2-RSA the RSA2 key or it means something else? There I see an option SSH2-RSA, SSH1-RSA.
