Help on module _ssl: NAME _ssl MODULE REFERENCE https://docs.python.org/3.10/library/_ssl.html The following documentation is automatically generated from the Python source files. It may be incomplete, incorrect or include features that are considered implementation detail and may vary between Python implementations. When in doubt, consult the module reference at the location listed above. DESCRIPTION Implementation module for SSL socket operations. See the socket module for documentation.

See RFC 4086. RAND_bytes(n, /) Generate n cryptographically strong pseudo-random bytes. RAND_pseudo_bytes(n, /) Generate n pseudo-random bytes. Return a pair (bytes, is_cryptographic). is_cryptographic is True if the bytes generated are cryptographically strong. RAND_status() Returns True if the OpenSSL PRNG has been seeded with enough data and False if not. It is necessary to seed the PRNG with RAND_add() on some platforms before using the ssl() function. get_default_verify_paths() Return search paths and environment vars that are used by SSLContext's set_default_verify_paths() to load default CAs. The values are 'cert_file_env', 'cert_file', 'cert_dir_env', 'cert_dir'. nid2obj(nid, /) Lookup NID, short name, long name and OID of an ASN1_OBJECT by NID. txt2obj(txt, name=False) Lookup NID, short name, long name and OID of an ASN1_OBJECT. By default objects are looked up by OID. With name=True short and long name are also matched.
