You can share parts of a secret with multiple people, so only some of them need to agree to see the secret.
|
|
|
|
Install `ssss`, then decide on the total number of secrets (`N`), and the threshold of people who must share their shard of the secret in order to reveal the secret.
|
|
|
|
```bash
|
|
N=5
|
|
T=3
|
|
FILE=secret.txt
|
|
fortune | ssss-split -t $T -n $N > $FILE
|
|
```
|
|
Each shard is a line inside secret.txt.
|
|
|
|
Check it's working:
|
|
|
|
```bash
|
|
head -n $T $FILE | ssss-combine -t $T
|
|
tail -n $T $FILE | ssss-combine -t $T
|
|
```
