Hi,

 

Ssl_pkix:decode_rsa_keyfile is returning undefined because it requires
two parameters, namely Key File and Password

Hi,
there is not yet a public api for this in OTP. However, the
undocumented, unsupported function ssl_pkix:decode_rsa_keyfile/2 does
just this. It reads a .pem keyfile and returns a record with exponent
and modulus, and other fields. It is unsupported, so it might be moved
(or even removed) in future releases of OTP.

Hi,

   As far as I know the crypto module (app) handles rsa's private keys
as a list of two binaries (exponent and modulus). How can I obtain these
from base64 encoded *.pem files?
