02:28:36 koha_1 | WARNING: The key derivation method "opensslv1" is deprecated. Using -pbkdf=>'pbkdf2' would be better. 02:28:36 koha_1 | Pass -nodeprecate=>1 to inhibit this message. 02:28:36 koha_1 | at /kohadevbox/koha/Koha/Patron.pm line 3216. From the doc https://metacpan.org/pod/Crypt::CBC -pbkdf The passphrase-based key derivation function used to derive the encryption key and initialization vector from the provided passphrase. For backward compatibility, Crypt::CBC will default to "opensslv1", but it is recommended to use the standard "pbkdf2"algorithm instead. If you wish to interoperate with OpenSSL, be aware that different versions of the software support a series of derivation functions.
