Doc Type: Bug Fix
Doc Text:
When Federal Information Processing Standards (FIPS) mode was enabled on a system, key-based authentication was always unsuccessful. This was caused by the newly introduced pubkey_key_verify() verification function, which did not take into consideration the fact that it was running in a FIPS environment. With this update, the pubkey_key_verify() function has been modified to respect FIPS, and authentication using an RSA key is now successful without any issues when FIPS mode is enabled.
