[1.1.1] Fix PEM_write_bio_PrivateKey_traditional() to not output PKCS#8 #12729
Conversation
PEM_write_bio_PrivateKey_traditional() uses i2d_PrivateKey() to do the actual encoding to DER. However, i2d_PrivateKey() is a generic function that will do what it can to produce output according to what the associated EVP_PKEY_ASN1_METHOD offers. If that method offers a function 'old_priv_encode', which is expected to produce the "traditional" encoded form, then i2d_PrivateKey() uses that. If not, i2d_PrivateKey() will go on and used more modern methods, which are all expected to produce PKCS#8. To ensure that PEM_write_bio_PrivateKey_traditional() never produces more modern encoded forms, an extra check that 'old_priv_encode' is non-NULL is added. If it is NULL, an error is returned.
