With OpenSSL 3.x I get Error decrypting CMS structure 400755B1327F0000:error:1C800064:Provider routines:ossl_cipher_unpadblock:bad decrypt:../providers/implementations/ciphers/ciphercommon_block.c:129: If I swap cms for smime it changes to
Error decrypting PKCS#7 structure rest of the error stays the same. For all I know it has to do with some kinde of deprecated stuff in OpenSSL 3.x so you'd need to add something to the comand to enable legacy stuff. Using OpenSSL 1.1.1n however doesn't change much: Error decrypting CMS structure 139958493545792:error:06065064:digital envelope routines:EVP_DecryptFinal_ex:bad decrypt:../crypto/evp/evp_enc.c:610: The private key file is a PEM RSA key. Already checked that the reason can't be the wrong kind of line breaks (those Windows line breaks) inside the key file, since that was mentioned to be a possible reason. But the key file is as it's supposed to be.
