Public bug reported:
I found out that md4 algorithm does not work while being reported as
available.
Test Python script:
```
import hashlib
hashlib.algorithms_available
assert 'md4' in hashlib.algorithms_available
hashlib.new('md4', b"text")
```
This script should produce report like this:
```
$ python3
Python 3.8.10 (default, Nov 26 2021, 20:14:08)
[GCC 9.3.0] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import hashlib
>>> hashlib.algorithms_available
{'blake2s', 'sha3_224', 'sha512_224', 'sha224', 'md4', 'sha3_256', 'sha512',
'sha3_512', 'blake2b', 'shake_128', 'whirlpool', 'sha3_384', 'sha256', 'sha1',
'md5-sha1', 'sha384', 'shake_256', 'sm3', 'ripemd160', 'sha512_256', 'md5'}
>>> assert 'md4' in hashlib.algorithms_available
>>> hashlib.new('md4', b"text")
<md4 HASH object @ 0x7fc374058f30>
>>>
```
But for Jammy it crashes:
```
