dtool: Upgrade default encryption algorithm to AES-256 (#1337)

Browse Source 
The Blowfish cipher is no longer available on OpenSSL 3.x by default. It requires enabling the legacy cipher suite, which is compiled separately from the main OpenSSL library. AES-256 is a good replacement cipher that has hardware support in most newer computers. AES-256 is also available in OpenSSL 1.0.2.
