If you want to digitally sign your e-mail but not provide a password to unlock your keychain every time (for example, because you want to send Automator e-mails) you can do this in a few easy steps. | |
1. Open Keychain Access | |
2. Under the Keys category, find the private key associated with your e-mail certificate | |
3. Double click on it to open its info | |
4. Open the Access Control tab, providing credentials if asked | |
5. Select the Allow all applications to access this item radio button and then click Save Changes | |
Your mail client will no longer need to elevate privileges to access the private key and will therefore be able to sign and decrypt your mail messages without password. | |
Be aware the obvious security ramifications of this are that anyone who gains momentary access to your machine will be able to copy this private key for abuse. However, a persistent threat could still eventually gain access to this key through a local social engineering attack or by using a keylogger and waiting for you to legitimately open the key. |
