Specifying the curve parameters using ASN.1 object identifiers, which use one of the FIPS-approved curves, still works in FIPS mode.	Story Points:	---

Description Alicja Kario 2022-02-25 14:57:45 UTC

Description of problem:
When system is configured to work in FIPS mode, the ECDSA operations with explicit parameters don't work. This is in contrast to RHEL-8

Version-Release number of selected component (if applicable):
openssl-3.0.1-13.el9

How reproducible:
always

Steps to Reproduce:
1. set up FIPS mode
2. openssl ecparam -out ecparams.pem -param_enc explicit -name P-256
3. openssl ecparam -in ecparams.pem -check

Actual results:
Could not read params of EC parameters from ecparams.pem
80CB0D2AEB7F0000:error:1608010C:STORE routines:ossl_store_handle_load_result:unsupported:crypto/store/store_result.c:151:

Expected results:
passed, same for key generation, signature creation, and signature verification

Comment 7 Dmitry Belyavskiy 2022-04-27 11:47:24 UTC

Upstream has forbidden the explicit FIPS parameters in FIPS mode. See https://github.com/openssl/openssl/pull/17998

Comment 9 Alicja Kario 2022-05-06 15:50:15 UTC

We've decided to follow upstream in this behaviour, as such explicit curve parameters will no longer work in FIPS mode.
Explicit curve parameters will be supported in non-FIPS mode, see bug 2066412.

Comment 24 Clemens Lang 2023-06-05 16:07:27 UTC

RHEL 9.1 contains openssl-3.0.1-43.el9_0.
