Mark Post 943bbccb27 Accepting request 801383 from home:markkp:branches:devel:openSUSE:Factory
- Added the following patches for FIPS certification (bsc#1162533)
  * libica-sles15sp2-FIPS-introduce-HMAC-based-library-integrity-check.patch
  * libica-sles15sp2-FIPS-hmac-key.patch
- Added a BuildRequires for the fipscheck package.
- Made a couple of changes to the spec file based upon recommendations
  by spec-cleaner.
- Added the following patches for FIPS certification.
  * libica-sles15sp2-Fix-DES-and-TDES-key-length.patch
    (bsc#1166071) Although a DES key has only 56 effective bits,
     all 64 bits must be considered, because the parity bits are
     spread over all 8 bytes of the key.
  * libica-sles15sp2-FIPS-provide-output-iv-as-required-by-FIPS-tests.patch
    (bsc#1166210) FIPS tests require the output iv to be the iv
    resulting from decrypting the last block with a zero iv as input.
  * libica-sles15sp2-icainfo-bugfix-for-RSA-and-EC-related-info-for-softw.patch
    (bsc#1166224) The output from icainfo never shows 'yes' for
    RSA ME, RSA CRT, ECDH, ECDSA sign, ECDSA verify, and ECKGEN,
    due to the missing ICA_FLAG_SW flag in the icaList.

Although a DES key has only 56 effective bits, all 64 bits must be
considered, because the parity bits are spread over all 8 bytes of
the key.
