Description
Hello, thank you for your continued development of the dartssh2 module!
I've noticed that the SSHKeyPair.fromPem function we use to read the private key fails to parse a few different types of private keys.
I would like to see private keys with these formats supported.
Regards,
The key formats that fail include:
A. Any private key that uses the DSA algorithm
