3.3. Get Private Key From PEM String Now that we know how to read a public key, the algorithm to read a private key is very similar. We’ll use a PEM encoded private key in PKCS8 format. Let’s see what the header and footer look like: ...
---BEGIN RSA PRIVATE KEY---Base64–encoded private key---END RSA PRIVATE KEY--- 下面的示例介绍一个 PEM 编码的椭圆曲线私有密钥。根据您创建密钥的方式,可能不包含参数块。如果包含参数块,ACM 会在导入过程中使用此密钥前将其删除。 ---BEGIN EC...
