## Hash functions

| **Function Name**              | **Description**                                  |
| ------------------------------ | ------------------------------------------------ |
| [hash\_md5()](#hash-md5)       | Returns a MD5 hash value for the input value.    |
| [hash\_sha1()](#hash-sha1)     | Returns a sha1 hash value for the input value.   |
| [hash\_sha256()](#hash-sha256) | Returns a SHA256 hash value for the input value. |
| [hash\_sha512()](#hash-sha512) | Returns a SHA512 hash value for the input value. |

## hash\_md5()

Returns an MD5 hash value for the input value.

### Arguments

* source: The value to be hashed.

### Returns

The MD5 hash value of the given scalar, encoded as a hex string (a string of characters, each two of which represent a single Hex number between 0 and 255).

### Examples

```kusto
hash_md5(source)
```

```kusto
['sample-http-logs']
| project md5_hash_value = hash_md5(content_type)
```

* Result

```json
{
  "md5_hash_value": "b980a9c041dbd33d5893fad65d33284b"
}
```

## hash\_sha1()

Returns a SHA1 hash value for the input value.

### Arguments

* source: The value to be hashed.

### Returns

The sha1 hash value of the given scalar, encoded as a hex string

### Examples

```kusto
hash_sha1(source)
```

```kusto
['sample-http-logs']
| project sha1_hash_value = hash_sha1(content_type)
```

  "sha1_hash_value": "9f9af029585ba014e07cd3910ca976cf56160616"
}
```

## hash\_sha256()

Returns a SHA256 hash value for the input value.

### Arguments

* source: The value to be hashed.

### Returns

The sha256 hash value of the given scalar, encoded as a hex string (a string of characters, each two of which represent a single Hex number between 0 and 255).

### Examples

```kusto
hash_sha256(source)
```

```kusto
['sample-http-logs']
| project sha256_hash_value = hash_sha256(content_type)
```

* Result

```json
{
  "sha256_hash_value": "bb4770ff4ac5b7d2be41a088cb27d8bcaad53b574b6f27941e8e48e9e10fc25a"
}
```

## hash\_sha512()

Returns a SHA512 hash value for the input value.

### Arguments

* source: The value to be hashed.

### Returns

The sha512 hash value of the given scalar, encoded as a hex string (a string of characters, each two of which represent a single Hex number between 0 and 511).

### Examples

```kusto
hash_sha512(source)
```

```kusto
['sample-http-logs']
| project sha512_hash_value = hash_sha512(status)
```
