Incompatibility
In Fujitsu Enterprise Postgres 15 SP2 and later, the PostgreSQL extension pgcrypto does not support the use of the encryption algorithm, which has become a legacy algorithm in the OpenSSL3 family, by default.
The encryption algorithms that are no longer available by default are:
BF
CAST5
DES-ECB
DES-CBC
MD4
Whirlpool
Action method
If you use a legacy OpenSSL provider, create an OpenSSL configuration file and set the parameters in postgresql.conf. Refer to "Settings for Using Legacy OpenSSL Providers" in the Installation and Setup Guide for Server for information .
