Hi Simon: I apologize but the solution I described in my previous message is not valid. When I tested it, I forgot to configure libssh2 for libgcrypt, and when I did the parse problems returned.
Best Regards, Paul R. ********** PREVIOUS MESSAGE ******** Hi Simon: I discovered a simple solution. It relies on the fact that libgcrypt can decode RSA version 1 private keys. The solution is to specify "-t rsa1" when you run ssh-keygen. PS: You hints make finding the solution easy ! Best Regards, Paul R.
