Contributions welcome. It's a good idea to encrypt your files locally before sending them out, even if you trust the service. Here's a short how-to. Encrypt with 256 bit AES: openssl enc -aes-256-cbc -salt -in <infile> -out <outfile> Decrypt: openssl enc -aes-256-cbc -d -in <infile> -out <outfile> Skip the -in and -out options to make openssl use STDIN or STDOUT . See man enc for information on available ciphers. aes-256-cbc and bf are what I generally use.
