# Encrypting a file
|
|
|
|
|
|
2020-02-07 23:06:20 +00:00
|
|
|
> gpg -r malinfreeborn@tutamail.com -e file
|
2020-01-02 00:04:35 +00:00
|
|
|
|
|
|
|
|
`-r` specifies the recipient.
|
|
|
|
|
|
|
|
|
|
Check you have an encrypted version of your file.
|
|
|
|
|

# Changing Expiration Dates
|
|
|
|
|
|
|
|
|
|
gpg --list-keys
|
|
|
|
|
|
|
|
|
|
... and then use the second part of 'pub', which is the ID. But that's not appearing here so... on with gpg2?
|
|
|
|
|
|
|
|
|
|
# Making encrypted files with a local password
|
|
|
|
|
|
|
|
|
|
Make a password with a password (cypher encryption).
|
|
|
|
|
|
|
|
|
|
> gpg -c --output passwords.txt
|
|
|
|
|
|
|
|
|
|
or
|
|
|
|
|
|
|
|
|
|
> gpg -c > passwords.txt
|
|
|
|
|
|
|
|
|
|
Put in a password.
|
|
|
|
|
|
|
|
|
|
Write message then stop with Ctrl+d.
|
|
|
|
|
|
|
|
|
|
Get the message back out the file with:
|
|
|
|
|
|
|
|
|
|
> gpg -d passwords.txt
|
|
|

# Circles of Trust
|
|
|
|
|
|
|
|
|
|
Search for a key at any key store:
|
|
|
|
|
|
|
|
|
|
> gpg --keyserver sks.hklbgd.org --search-keys nestorv
|
|
|
|
|
|
|
|
|
|
Once you've made a decision about someone:
|
|
|
|
|
|
|
|
|
|
> gpg --list-keys
|
|
|
|
|
|
|
|
|
|
You get something like this:
|
|
|
|
|
|
|
|
|
|
```
|
|
|
|
|
pub rsa3072 2021-08-15 [SC] [expires: 2023-08-15]
|
|
|
|
|
CD30421FD825696BD95F1FF644C62C57B790D3CF
|
|
|
|
|
uid [ultimate] Malin Freeborn <malinfreeborn@posteo.net>
|
|
|
|
|
sub rsa3072 2021-08-15 [E] [expires: 2023-08-15]
|
|
|
|
|
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
Notice the long, ugly, string - CD30421FD825696BD95F1FF644C62C57B790D3CF - and how horribly ugly it is.
|
|
|
|
|
This is a fingerprint.
|
|
|
|
|
|
|
|
|
|
You can now decide the trust level (this stays on your computer).
|
|
|
|
|
|
2021-11-09 01:36:24 +00:00
|
|
|
> gpg --edit-key (some fingerprint)
|
2021-10-21 19:46:03 +00:00
|
|
|
|
2021-10-21 19:48:22 +00:00
|
|
|
Once you're in the interface, type `trust`.
|
2021-10-21 19:46:03 +00:00
|
|
|
|
|
|
|
|
> gpg --sign-key alice@posteo.net
|
|
|
|
|
|
2021-11-09 01:36:24 +00:00
|
|
|
Then send those trusted keys up to a server, so people can see you have verified them:
|
|
|
|
|
|
|
|
|
|
> gpg --keyserver sks.hklbgd.org --send-keys 024C6B1C84449BD1CB4DF7A152295D2377F4D70F
|
|
|
|
|
|
2021-10-21 19:46:03 +00:00
