openssl-1_1/openssl-rsakeygen-minimum-distance.patch
Vítězslav Čížek 02427a3414 - Renamed from openssl-1_1_0 (bsc#1081335)
* All the minor versions of the 1.1.x openssl branch have the same
    sonum and keep ABI compatibility

- Remove bit obsolete syntax
- Use %license macro

- Don't disable afalgeng on aarch64

- Add support for s390x CPACF enhancements (fate#321518)

  * 0013-crypto-aes-asm-aes-s390x.pl-add-CFI-annotations-KMA-.patch

- Do not filter pkgconfig() provides/requires.

- Obsolete openssl-1_0_0 by openssl-1_1_0: this is required for a
  clean upgrade path as an aid to zypp (boo#1070003).

- Update to 1.1.0g
