OpenSSL Cheat Sheet
|
|
===================
|
|
|
|
## Generate Self-Signed Certificate and Private Key
|
|
|
|
```shell
|
|
openssl genrsa -des3 -passout pass:x -out server.pass.key 2048 && openssl rsa -passin pass:x -in server.pass.key -out server.key && openssl req -new -key server.key -out server.csr
|
|
openssl x509 -req -days 365 -in server.csr -signkey server.key -out server.crt
|
|
```
|
|
|
|
- Use `server.crt` and `server.key`
|
|
|
|
### Encypt/Decrypt file
|
|
|
|
```
|
|
# Encrypt
|
|
openssl aes-128-cbc -a -e -pass pass:test -in vars -out vars.enc
|
|
# Puts encrypted data into vars.enc file
|
|
|
|
# Decrypt
|
|
openssl aes-128-cbc -a -d -pass pass:test -in vars.enc
|
|
# Outputs decrypted data to STDOUT
|
|
```
|
|
|
|
NOTE: See `openssl passpharse arguments` for information on using the password on the commandline. It can be changed to a file or an environment variable.
