# Hash
Creates a new MD5 hash object.
Call `update(data)` to feed bytes or strings into the hash, then
`digest()` for raw bytes or `hexdigest()` for the hex-encoded string.
# Examples
```python theme={null}
load("@std//hash.axl", "md5")
h = md5()
h.update("hello world")
h.hexdigest() # "5eb63bbbe01eeed093cb22bb8f5acdc3"
```
`function` **sha1**
Creates a new SHA-1 hash object.
Call `update(data)` to feed bytes or strings into the hash, then
`digest()` for raw bytes or `hexdigest()` for the hex-encoded string.
# Examples
```python theme={null}
load("@std//hash.axl", "sha1")
h = sha1()
h.update("hello world")
h.hexdigest() # "2aae6c35c94fcfb415dbe95f408b9ce91ee846ed"
```
`function` **sha224**
Creates a new SHA-224 hash object.
Call `update(data)` to feed bytes or strings into the hash, then
`digest()` for raw bytes or `hexdigest()` for the hex-encoded string.
# Examples
```python theme={null}
load("@std//hash.axl", "sha224")
h = sha224()
h.update("hello world")
h.hexdigest() # "2f05477fc24bb4faefd86517156dafdecec45b8a..."
```
`function` **sha256**
Creates a new SHA-256 hash object.
Call `update(data)` to feed bytes or strings into the hash, then
`digest()` for raw bytes or `hexdigest()` for the hex-encoded string.
# Examples
```python theme={null}
load("@std//hash.axl", "sha256")
h = sha256()
h.update("hello world")
h.hexdigest()
# "b94d27b9934d3e08a52e52d7da7dabfac484efe37a5380ee9088f7ace2efcde9"
```
`function` **sha384**
Creates a new SHA-384 hash object.
Call `update(data)` to feed bytes or strings into the hash, then
`digest()` for raw bytes or `hexdigest()` for the hex-encoded string.
# Examples
```python theme={null}
load("@std//hash.axl", "sha384")
h = sha384()
h.update("hello world")
h.hexdigest() # 96-char hex string
```
`function` **sha512**
Creates a new SHA-512 hash object.
Call `update(data)` to feed bytes or strings into the hash, then
`digest()` for raw bytes or `hexdigest()` for the hex-encoded string.
# Examples
```python theme={null}
load("@std//hash.axl", "sha512")
h = sha512()
h.update("hello ")
h.update("world")
h.hexdigest() # 128-char hex string
```
`function` **blake2b**
Creates a new BLAKE2b-512 hash object.
Call `update(data)` to feed bytes or strings into the hash, then
`digest()` for raw bytes or `hexdigest()` for the hex-encoded string.
# Examples
```python theme={null}
load("@std//hash.axl", "blake2b")
h = blake2b()
h.update("hello world")
h.digest() # raw 64-byte digest as bytes
```
`function` **blake2s**
Creates a new BLAKE2s-256 hash object.
Call `update(data)` to feed bytes or strings into the hash, then
`digest()` for raw bytes or `hexdigest()` for the hex-encoded string.
# Examples
```python theme={null}
load("@std//hash.axl", "blake2s")
h = blake2s()
h.update("hello world")
h.digest() # raw 32-byte digest as bytes
```
