For creating and verifying PKCS#1 v1.5 signatures in a pre-hashed
manner, we used the legacy RSA_sign and RSA_verify functions, which
bypass the system-wide disablement of SHA-1 and shorter RSA key length
usage inconsistently with the OpenSSL 3.0 default on RHEL.
This switches to using our _goboringcrypto_EVP_{sign,verify}_raw,
which internally use EVP_PKEY_ functions.

This switches _goboringcrypto_RSA_generate_key_fips to using EVP_PKEY_keygen function instead of RSA_generate_key_ex. The accessors functions around the RSA * type, such as RSA_get0_crt_params, are still used, though they are not a cryptographic operation so this patch leaves it as they are for now.

@ueno Is this PR still valid? If so I'll ask some of the MSFT folks to review. |
