PEM parser.

pem's Issues

PEM:READ-FROM-FILE returns NIL on PKCS#8 keys

CL-USER> (pem:read-from-file #P"~/priv4096.pem")
NIL

whenever the file contains a private key in form:

-----BEGIN PRIVATE KEY-----
MIIJQwIBADANBgk... (base64 encoded data)
-----END PRIVATE KEY-----

Package OPTIMA does not exist

on (ql:quickload "pem") got error: Package OPTIMA does not exist.

Probably need to add (:import-from #:optima) to pkey.lisp

`read-from-file` fails on openssl generated private key.

if i run openssl genrsa -out private.pem 2048 to make a RSA key saved to private.pem, i'm unable to read it with pem:read-from-file.

firstly, the file's header is "BEGIN PRIVATE KEY", not "BEGIN RSA PRIVATE KEY", so the assoc call fails.

but even if i add RSA to the pem file, or remove the RSA from the assoc string that does the check, read-private-key still fails and i get the Unexpected format error.

do you have any ideas about how to get this working? or how to create a private key pem file in a way that this library will happily read it?

(apologies if this is glaringly obvious, i'm no crypto expert.)

Support for ECDSA

I would like to use e.g. ES256 in some applications. See fukamachi/jose#3. For Jose to support this we have to update pem first. Before sending a PR i wanted to ask how the implementation should be structured:

• Should we integrate ECDSA in read-from-file? This works simple with private key files but a bit more tricky with public key files.
• Or would you prefer to have new exported function such as read-ec-from-file?

write ironclad key back to pem?

is there a way pem and/or ironclad can write rsa-public/private-key objects back to pem format?

i'm trying to work out http signatures in CL.
