Parsing keys and certificates
The read_key function (private keys) and read_pubkey (public keys)
support both SSH pubkey format and OpenSSL PEM format (base64 data with a --BEGIN
and ---END header), and automatically convert where necessary. The functions assume
a single key per file except for read_cert_bundle which supports PEM files
with multiple certificates.
read_key(file, password = askpass, der = is.raw(file)) read_pubkey(file, der = is.raw(file)) read_cert(file, der = is.raw(file)) read_cert_bundle(file) read_pem(file)
file |
Either a path to a file, a connection, or literal data (a string for pem/ssh format, or a raw vector in der format) |
password |
A string or callback function to read protected keys |
der |
set to |
Most versions of OpenSSL support at least RSA, DSA and ECDSA keys. Certificates must conform to the X509 standard.
The password argument is needed when reading keys that are protected with a
passphrase. It can either be a string containing the passphrase, or a custom callback
function that will be called by OpenSSL to read the passphrase. The function should
take one argument (a string with a message) and return a string. The default is to
use readline which will prompt the user in an interactive R session.
An object of class cert, key or pubkey which holds the data
in binary DER format and can be decomposed using as.list.
