# BlockCrypt (beta)
2+
3+
## Encrypt one or more secrets with plausible deniability by design.
4+
5+
BlockCrypt uses Base58 to render one or more AES-256-CBC-encrypted secrets indistinguishable from each other and padding yielding ciphertext “blocks” of fixed size that one can print as QR codes.
6+
7+
## Installation
8+
9+
```console
10+
$ npm install blockcrypt
11+
```
12+
13+
## Usage (simplified for demonstration purposes)
14+
15+
```typescript
16+
import { encrypt, decrypt, Secret } from "./index.js"
17+
18+
const secrets: Secret[] = [
19+
{
20+
message:
21+
"trust vast puppy supreme public course output august glimpse reunion kite rebel virus tail pass enhance divorce whip edit skill dismiss alpha divert ketchup",
22+
passphrase: "lip gift name net sixth",
23+
},
24+
{
25+
message: "this is a test\nyo",
26+
passphrase: "grunt daisy chow barge pants",
27+
},
28+
{
29+
message: "foo",
30+
passphrase: "decor gooey wish kept pug",
31+
},
32+
]
33+
34+
const block = await encrypt(secrets, kdf)
