Question
Our application needs to encrypt/decrypt files using (for instance) Blowfish encryption algorithm. We know bcrypt could be a good choice, but it cannot be called directly from our application (as it prompts for key phrase).
Which is the best existing option?
We prefer a Windows tool, though Linux would be good as well.
Solution
http://www.openssl.org/docs/crypto/blowfish.html programming interface
http://www.openssl.org/docs/apps/enc.html command line interface
Example:
openssl enc -base64 -e -bf-cbc -in <infile> -out <outfile> -kfile <passphrase file>
(replace -e
with -d
to decrypt)
OTHER TIPS
I coudln't find one I liked; so I wrote one in Go. Here it is: https://prologic.github.io/fish/
Example:
$ echo 'Hello World' | fish -e -k mysecret -
Pretty easy to install with:
$ go get github.com/prologic/fish
Also supports both Blowfish and the newer Twofish
