Description Clemens Lang 2023-02-08 17:39:42 UTC 
Description of problem:
OpenSSL uses functions that do not compute a digest (for signatures) or an approved padding method (for encryption) for pairwise consistency tests of new EC or RSA keys (or DSA keys, but we do not certify DSA).

See

- crypto/ec/ec_key.c, function ecdsa_keygen_pairwise_test, which calls ECDSA_do_sign.
- crypto/rsa/rsa_gen.c, function rsa_keygen_pairwise_test, which calls RSA_public_encrypt and RSA_private_decrypt

These should instead use EVP_DigestSign and EVP_DigestVerify.


Version-Release number of selected component (if applicable):
openssl-3.0.1-44.el9_0.1

How reproducible:
Inspect source code, find use of ECDSA_do_sign, RSA_public_encrypt, RSA_private_decrypt

Expected results:
Pairwise consistency tests use functions that compute a digest before signing it.

Additional info:
While we could possibly use RSA-OAEP as pairwise encryption/decryption test, that would require us to add another tests for RSA signatures. It's best to just use RSA signatures instead. AFAIR the FIPS 140-3 IG allow us to skip the PCT for encryption and decryption if we have a signature PCT.
