Parameters

val:DerValue: the DerValue

KeyIdentifier	back to summary
public KeyIdentifier(PublicKey pubKey) throws IOException Creates a KeyIdentifier from a public-key value. From RFC 5280: Two common methods for generating key identifiers from the public key are: The keyIdentifier is composed of the 160-bit SHA-1 hash of the value of the BIT STRING subjectPublicKey (excluding the tag, length, and number of unused bits). The keyIdentifier is composed of a four bit type field with the value 0100 followed by the least significant 60 bits of the SHA-1 hash of the value of the BIT STRING subjectPublicKey. This method supports method 1. Parameters pubKey:PublicKey the public key from which to construct this KeyIdentifier Exceptions IOException: on parsing errors
