I never can remember this:
Removing a passphrase from your id_rsa key

1. Backup your id_rsa file! Then,
2. openssl rsa -in ~/.ssh/id_rsa -out ~/.ssh/id_rsa_new
3. cp ~/.ssh/id_rsa ~/.ssh/id_rsa.backup
4. rm ~/.ssh/id_rsa
5. cp ~/.ssh/id_rsa_new ~/.ssh/id_rsa
6. chmod 400 ~/.ssh/id_rsa

Removing a passphrase from an SSL server key

1. Create a private key: openssl genrsa -des3 -out server.key 1024
2. Generate a CSR: openssl req -new -key server.key -out server.csr
3. Remove passphrase from key:
   • cp server.key server.key.org
   • openssl rsa -in server.key.org -out server.key
