OpenSSL wrap

ruby-talk

Hello,

To encrypt a file i use the following command line, a password will be prompted :
openssl enc -aes-256-cbc -in un_encrypted.data -out encrypted.enc

The same, to decrypt a file, i use the following command line, a password will be prompted :
openssl enc -d -aes-256-cbc -in encrypted.enc -out un_encrypted.data

Is there a Ruby Gem for that ?

Thank you very much anyway.

Cheers,

Marc.

Hi Marc,

just out of curiosiy, why do you need to bypass the shell ?

Do you need to run in Windows or some other platform not having
the "openssl" command ?

If not, you could do something as easy as:

···

------------------------------------------------
inFile = "un_encrypted.data"
outFile = "un_encrypted.data"
cmd = "openssl enc -aes-256-cbc -in #{inFile} -out #{outFile}"
system(cmd)
------------------------------------------------

CAVEAT. i did not run the snippet, there could be typos !

Bye
Nicola
