first round-trip tests

feat: made asn1 structures readable

refacto: adapted existing functions accordingly

feat/pkcs12: added symmetric_decrypt

feat: deserialize 3 possible encodings

feat: handling AES-128

feat: raise error when no recipient is found

feat/pkcs7: added decanonicalize function

feat/asn1: added decode_der_data

feat/pkcs7: added smime_enveloped_decode

tests are the round-trip (encrypt & decrypt)

more tests for 100% python coverage

test support pkcs7_encrypt with openssl

added algorithm to pkcs7_encrypt signature

refacto: decrypt function is clearer

flow is more natural

refacto: added all rust error tests

refacto: added another CA chain for checking

fix: const handling

Refactor PKCS7Decryptor to pkcs7_decrypt

refacto: removed SMIME_ENVELOPED_DECODE from rust code

refacto: removed decode_der_data

adapted tests accordingly

removed the PEM tag check

added tests for smime_decnonicalize

one more test case

took comments into account

pem to der is now outside of decrypt

fix: removed test_support pkcs7_encrypt

added vector for aes_256_cbc encrypted pkcs7

feat: not using test_support decrypt anymore

added new vectors for PKCS7 tests

feat: using pkcs7 vectors

removed previous ones

fix: changed wrong function

feat: added certificate issuer check

test: generating the RSA chain

removed the vectors accordingly
