Class X509EncodedKeySpec

java.lang.Object extended by java.security.spec.EncodedKeySpec java.security.spec.X509EncodedKeySpec

All Implemented Interfaces:

public class 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 }

Since:

1.2
