Java parses various encoding key pairs (DER, PEM, OpenSSH public keys)

1. Der-encoded key pair Let's talk about DER encoding because JCE supports DER encoding key pair parsing. For details, see pkcs8encodedkeyspec and x509encodedkeyspec. DER encoding is a subset of the ASN.1 encoding rules. We do not know how to orchestrate the specific formats, but it is definitely a combination of regular binary codes. PKCS #8 defines the private key information syntax and the encryption Private Key syntax, while X509 defines the certificate specification, usually using DER and
