[v5,00/11] ima-evm-utils: Convert sign v2 from RSA to EVP_PKEY API

Message

Vitaly Chikunov June 18, 2019, 1:56 p.m. UTC

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.

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.
