Cipher: Doc suggests to persist generated key, but key cannot be accessed

[themightyoarfish]

I want to generate an RSA key with Poco. The doc for Cipher / CipherFactory says I should persist the generated key, how do I do this? As far as I can tell, the key is private in the Cipher class and its derived classes.

poco/Crypto/include/Poco/Crypto/Cipher.h

Line 48 in e4aaeac

/// once the Cipher is destroyed unless you persist the generated key and IV.

Dumb question, the doc literally generates a key that gets passed to the cipher.

Actually, RSAKey is deprecated. How can I generate an RSA key (and put it into an EVPPKey) with non-deprecated functions?

Ok dumb again, one can just use the EVPPKey constructor

  const EVPPKey random_key(EVP_PKEY_RSA, 2048);
