OpenJDK 1.23 · java.security.spec.X509EncodedKeySpec

This class represents the ASN.1 encoding of a public key, encoded according to the ASN.1 type SubjectPublicKeyInfo. The SubjectPublicKeyInfo syntax is defined in the X.509 standard as follows:

SubjectPublicKeyInfo ::= SEQUENCE {
  algorithm AlgorithmIdentifier,
  subjectPublicKey BIT STRING }
