write_der

write_pem

a public/private key or certificate object

string or callback function to set password (only applicable for
private keys).

password

file to write to. If <code>NULL</code> it returns the output as a string.

path

The <code>write_pem</code> functions exports a key or certificate to the standard
base64 PEM format. For private keys it is possible to set a password.

Bindings to OpenSSL libssl and libcrypto, plus custom SSH pubkey parsers.
    Supports RSA, DSA and NIST curves P-256, P-384 and P-521. Cryptographic signatures
    can either be created and verified manually or via x509 certificates. AES block
    cipher is used in CBC mode for symmetric encryption; RSA for asymmetric (public key)
    encryption. High-level envelope functions combine RSA and AES for encrypting arbitrary
    sized data. Other utilities include key generators, hash functions (md5, sha1, sha256,
    etc), base64 encoder, a secure random number generator, and 'bignum' math methods for
    manually performing crypto calculations on large multibyte integers.
