Hello wez.ash786,

Sorry, yes it is true that Putty format private keys are not supported in our products.

As found in the SecureCRT help topic "Secure Connections / Public-Key Authentication for SSH2":

Note: Public keys generated using VanDyke Software products comply with the established IETF draft specification defining the format of Secure Shell public key files. This does not guarantee that SecureCRT will work with public key files generated using other Secure Shell software implementations which may or may not comply with this specification.

Since there is no IETF specification defining the format of Secure Shell private key files, SecureCRT may not be able to use private key files generated with other implementations. It should also be noted that, since the private key generated by SecureCRT uses a different format from OpenSSH's private key, OpenSSH cannot use a VanDyke Software generated private key.

SecureCRT supports SSH2 public-private key files generated with VanDyke Software products and the public-private key files generated with the OpenSSH ssh-keygen utility.
There are several posts in the VanDyke forums that detail how to convert Putty public key files (.ppk) to a format that can be used with our products.

Here are two other threads that contain the steps to convert .ppk to the appropriate format:

The ability to use a PuTTY PPK file for public-key authentication has been added to a pre-beta version of SecureCRT. If you'd like to try it, please send email to Maureen.Jett@vandyke.com.
