The documentation for Erlang’s
:cryptomodule is a good place to start:des_cbc, when available (see below)pkcs_paddingBeware: the algorithms available from
:cryptoare limited to ones provided by the OpenSSL library that Erlang is linked against. Some versions of OpenSSL have dropped support for old / deprecated ones like DES.smathy
I mean for every definition of “encrypt” that has any value, nothing can use DES to encrypt anything.
ex_cryptois a nice elixir interface to the underlying erlangcryptlibrary. You can of course usecryptdirectly (assuming an old systemcrypt(3)) for DES but do so at your own riskGot that all wrong, nevermind me.

Thank you @al2o3cr. I shall look it up now…

Is there any special way of setting the value below as an initialization vector for des_cbc?
0x12, 0x34, 0x56, 0x78, 0x90, 0xAB, 0xCD, 0xEF?
