Convert sign v2 from RSA API (with manual formatting PKCS1) to more generic
EVP_PKEY API, allowing to generate more types of OpenSSL supported signatures.
This is done to enable EC-RDSA signatures, which are already supported in the
Kernel. With some small fixes.
All patches tested on x86_64 to not break anything.
Changes since v5:
- Squash calc keyid v2 with cmd_import patch.
- Add log_err messages to verify_hash_v2 and sign_hash_v2.
- Fix sign and hash generation error processing to show errors instead
of assert failures.
Changes since v4:
- Split conversion into more patches, as suggested by Mimi Zohar.
- Small fixes suggested by Mimi Zohar.
Changes since v3:
- As suggested by Mimi Zohar this is v3 splitted into several patches to
simplify review. No code changes.
Changes since v2:
- Just rebase over newer commits.
Changes since v1:
- More key neutral code in calc_keyid_v1().
- Fix uninitialized sigsize for EVP_PKEY_sign().
- Fix memory leaks for openssl types.
