echo -e "default-cache-ttl 1\nmax-cache-ttl 1" > ~/.gnupg/gpg-agent.conf; echo RELOADAGENT | gpg-connect-agent

```

### Encrypt
|
|
1. ```gpg --full-generate-key```
|
|
2. ```gpg --export -a "thek4n" > public.key``` -a ASCII
|
|
3. ```gpg --fingerprint "thek4n"``` (send fingerprint IRL)
|
|
4. ```gpg -seaR "john" -u "thek4n" file``` -s sign, -e asymmetric, -a ASCII, -R ciphered receiver, -u secret key
|
|
|
|
### Decrypt
|
|
4. ```gpg --import public.key```
|
|
5. ```gpg --fingerprint "thek4n"``` (check fingerprint)
|
|
7. ```gpg -d --try-secret-key "john" file.asc > res.txt```
|
|
|
|
### Sign message (one file)
|
|
enc: ```gpg -u "thek4n" --clear-sign -s file``` -u secret key, --clear-sign ascii\
|
|
dec: ```gpg -d file.asc```
|
|
