获取X509的IssuerNameHash和IssuerKeyHash
我需要从X509 CA证书中获取以下内容：
- DER编码的公共密钥（不包括标签和长度）的主题公共密钥字段的哈希
- 发行者的哈希德（Hash）杰出的名称，必须在编码的DER编码上计算出 。 issuer's name field
I tried to use X509_issuer_name_hash and X509_pubkey_digest , but apparently they return not the results that I expect.
这个问题和发布的答案接近我要寻找的内容：我如何从PEM或DER证书中获得InsuerNameHash和IssuerKeyHash？，但是我想对如何在C ++和OpenSSL中进行此操作。
更新： x509_pubkey_digest正是我所需要的，我只是犯了一个错误转换为hexstring的错误。发行人的杰出名称的哈希仍然是打开的。
I need to get the following out of x509 CA certificates:
- the Hash of the DER encoded public key (excluding tag and length) of the subject public key field
- the hash of the issuers distinguished name, that must be calculated over the DER encoding of the issuer's name field
I tried to use X509_issuer_name_hash and X509_pubkey_digest , but apparently they return not the results that I expect.
This question and the answers posted is close to what I look for: How can I get issuerNameHash and issuerKeyHash from PEM or DER certificates? but I would like to have an explanation on how to do this in C++ and OpenSSL.
UPDATE: X509_pubkey_digest is exactly what i needed, I just made a mistake converting to hexstring. The hash of the issuer's distinguished name is still open though.
