Hi,

For our customers we make backups (like everyone else).
However, legal restrictions apply to the specific branche we work in. We are required to encrypt the data.

Thanks in advance...

As far as I know there is no tool in openssl you can just drop in to use a public key to encrypt a stream. If someone knows better please tell.

There is the smime-tool which can encrypt files, but I don't think this is what you want/need. One way to work around this problem (other than writing your own tool) might be a sequence of shell commands which may work like this:

   * Generate a key from /dev/random and store it in a file
   * Use this key to do openssl des3 ... like you did before
   * Encrypt the key using openssl smime with you client's certificate
   * Delete the unencrypted key (this might not be as trivial as it
     sounds if secutity requirements are high)

This way your customer could use the reverse procedure (decrypt key with openssl smime and decrypt data with the key) to recover the data.

Hope it helps,
Ted

This is great. So much thanks from me (and my customers LOL).
This is just what I needed. Shame I couldn't come up with it myself :D

Cheers,
