# Hash Generator

Generate cryptographic hashes from text input.

## Commands

```bash
devv hash "hello world" sha256
devv hash "hello world" sha512
devv hash "hello world" md5
echo "file contents" | devv hash - sha256
```

## Examples

```bash
# Hash a password for comparison
devv hash "mysecretpassword" sha256

# Hash a file
cat secret.txt | devv hash - sha512

# Quick MD5 checksum
echo "test" | devv hash - md5
```

## Output

```bash
$ devv hash "hello world" sha256
b94d27b9934d3e08a52e52d7da7dabfac484efe37a5380ee9088f7ace2efcde9

$ devv hash "hello world" md5
5eb63bbbe01eeed093cb22bb8f5acdc3
```

## Pipeline Usage

| Pipeline ID | Description |
|-------------|-------------|
| `hash-generator` | Hash the input (default: SHA-256) |

```bash
devv pipe exec "json-formatter | hash-generator sha256" '{"data":"secret"}'
devv pipe exec "base64-decode | hash-generator md5" "aGVsbG8="
```

### Options in pipelines

```
hash-generator sha256
hash-generator sha512
hash-generator md5
```

### Behavior

**Passthrough** — the original input is forwarded to the next pipeline step. The hash result is displayed but doesn't replace the data flowing through.

## Algorithms

| Algorithm | Output Length |
|-----------|-------------|
| `md5` | 32 characters |
| `sha256` | 64 characters (default) |
| `sha512` | 128 characters |
