Before you can decrypt something, you have to generate it! You can generate encrypted data with OpenSSL on the commandline using the enc command. To encrypt the contents of the current working directory (depending on the size of the files, this may take a while): # tar -czf - * | openssl enc -e -aes256 -out secured. (see the `enc' command for more details) If you do a "openssl ciphers -V" you should see the available ciphers on the UTM. If I understand you correctly, the installation of OpenSSL does not install ciphers along with it per se, and the ciphers would be installed by/used by the web server, and openssl is simply a tool to interface with these. Iterations have to be a minimum of 10000. Please describe the size of the encrypted files. enc -out some_file. The output of the enc command run with unsupported options (for example openssl enc -help) includes a list of ciphers, supported by your version of OpenSSL, including ones provided by configured engines. aes enter aes-128-cbc encryption password: 123 Verifying - enter aes-128-cbc encryption password: 123 $ openssl enc -a -aes128 -d < hosts.
