- FIPS: Deny SHA-1 signature verification in FIPS provider [bsc#1221365] * SHA-1 is not allowed anymore in FIPS 186-5 for signature verification operations. After 12/31/2030, NIST will disallow SHA-1 for all of its usages. * Add openssl-3-FIPS-Deny-SHA-1-sigver-in-FIPS-provider.patch - FIPS: RSA keygen PCT requirements. * Skip the rsa_keygen_pairwise_test() PCT in rsa_keygen() as the self-test requirements are covered by do_rsa_pct() for both RSA-OAEP and RSA signatures [bsc#1221760] * Enforce error state if rsa_keygen PCT is run and fails [bsc#1221753] * Add openssl-3-FIPS-PCT_rsa_keygen.patch - FIPS: Check that the fips provider is available before setting it as the default provider in FIPS mode. [bsc#1220523] * Rebase openssl-Force-FIPS.patch - FIPS: Port openssl to use jitterentropy [bsc#1220523] * Set the module in error state if the jitter RNG fails either on initialization or entropy gathering because health tests failed. * Add jitterentropy as a seeding source output also in crypto/info.c * Move the jitter entropy collector and the associated lock out of the header file to avoid redefinitions. * Add the fips_local.cnf symlink to the spec file. This simlink points to the openssl_fips.config file that is provided by the crypto-policies package. * Rebase openssl-3-jitterentropy-3.4.0.patch * Rebase openssl-FIPS-enforce-EMS-support.patch - FIPS: Block non-Approved Elliptic Curves [bsc#1221786] OBS-URL: https://build.opensuse.org/package/show/security:tls/openssl-3?expand=0&rev=110
