openssl 3.0: dont use deprecated functions

[uweber]

EVP_PKEY_get1_RSA, RSA_size and RSA_public_decrypt got deprecated in openssl 3.0, switch to EVP_PKEY_verify_recover

Code change mimics strongswan implementation from: src/libstrongswan/plugins/openssl/openssl_rsa_public_key.c

Also works with openssl 1.1.1n from debian buster

Sorry, I have no idea whats wrong with the commit messages and the codespell error is not caused by me:
074e1ceb src/vpnc.c (Ralph Schmieder 2019-01-09 16:56:07 -0800 3155) /* we should ignore resent pakets here.

So for commitlint rule, just make sure you follow the semantics of Conventional Commits.
codespell rule, on the other hand, checks for mispelled words: in that case, pakets should be packets.

[streambinder]

Please, amend the commit message to comply to Conventional Commit and now rebase off d20eec6 👍🏻

Thanks!
