- Plesk Onyx for Linux
OS is Red Hat Enterprise Linux.
Plesk installation fails with the following error:
PHP Warning: openssl_decrypt(): Unknown cipher algorithm; File: /usr/local/psa/admin/plib/AdminPassword/Unix.php, Line: 41
Unable to set admin password: Unable to change administrator's password: copy_file failed: md5_dgst.c(82): OpenSSL internal error, assertion failed: Digest MD5 forbidden in FIPS mode!
- FIPS-140-2 mode is enabled.
Currently, FIPS-140-2 mode is not supported by Plesk.
As a workaround disable FIPS-140-2 mode by following instructions from Red Hat - How to disable FIPS mode in RHEL.
