Hubert Kario wrote in https://bugzilla.redhat.com/show_bug.cgi?id=2054702 Description of problem: The hashlib.algorithms_available set includes algorithms like ripemd160 and whirlpool, those algorithms are not usable unless openssl legacy provider is loaded. Since it's not loaded, and the hashlib module won't load it, any attempt to use them fails. Version-Release number of selected component (if applicable): python3-3.9.10-1.el9.x86_64 openssl-3.0.1-5.el9.x86_64 How reproducible: always Steps to Reproduce: 0. start python3 1. from hashlib import algorithms_available 2. algorithms_available 3. import hashlib 4. a = {(name, hashlib.new(name).digest_size) for name in algorithms_available} Actual results: {'sha3_384', 'blake2s', 'sha384', 'sha512_224', 'md5', 'sha3_512', 'md5-sha1', 'sha3_256', 'shake_128', 'sm3', 'sha256', 'sha512', 'sha1', 'shake_256', 'blake2b', 'whirlpool', 'sha512_256', 'sha3_224', 'sha224', 'ripemd160', 'md4'} Traceback (most recent call last): File "/usr/lib64/python3.9/hashlib.py", line 164, in __hash_new return _hashlib.new(name, data, **kwargs) ValueError: [digital envelope routines] unsupported During handling of the above exception, another exception occurred: Traceback (most recent call last): File "<stdin>", line 1, in <module> File "<stdin>", line 1, in <setcomp> File "/usr/lib64/python3.9/hashlib.py", line 170, in __hash_new return __get_builtin_constructor(name)(data) File "/usr/lib64/python3.9/hashlib.py", line 127, in __get_builtin_constructor raise ValueError('unsupported hash type ' + name) ValueError: unsupported hash type whirlpool Expected results: {'sha3_384', 'blake2s', 'sha384', 'sha512_224', 'md5', 'sha3_512', 'md5-sha1', 'sha3_256', 'shake_128', 'sm3', 'sha256', 'sha512', 'sha1', 'shake_256', 'blake2b', 'sha512_256', 'sha3_224', 'sha224'} {('blake2b', 64), ('sha512', 64), ('md5-sha1', 36), ('sha3_512', 64), ('md5', 16), ('sha224', 28), ('shake_128', 0), ('sm3', 32), ('blake2s', 32), ('sha1', 20), ('shake_256', 0), ('sha512_256', 32), ('sha3_224', 28), ('sha3_256', 32), ('sha3_384', 48), ('sha384', 48), ('sha256', 32), ('sha512_224', 28)} Additional info: If the legacy provider is loaded, then the algorithms should be listed and should work. It may be caused by Python using the deprecated EVP_MD_do_all() method instead of the EVP_MD_do_all_provided() method ---------- components: Extension Modules, Library (Lib) messages: 415877 nosy: christian.heimes priority: normal severity: normal status: open title: hashlib.algorithms_available lists algorithms that are not available in OpenSSL 3.0 default provider type: behavior versions: Python 3.10, Python 3.11, Python 3.9 _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue47101> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
