OK. I think I understood what you are trying to do.. However, there is
no (intentional, at least ;-) support for reading public keys from files
outside the concept of reading a certificate that includes a public
key. The code that parses public key is used only to process the public
key inside a certificate or inside the TLS handshake. As such, no
standard format for public key stored in a file has been considered in
the code. You may need to add a new function to parse plain public keys.

Do you have any particular reason for not using X.509 certificates? Are
you assuming that the public keys are delivered over a trusted
out-of-band process and there is no need for PKI?
