Package com.google.crypto.tink.signature

Class SignaturePemKeysetReader

java.lang.Object

com.google.crypto.tink.signature.SignaturePemKeysetReader

All Implemented Interfaces:

KeysetReader

public final class SignaturePemKeysetReader
extends java.lang.Object
implements KeysetReader

SignaturePemKeysetReader reads digital signature keys in PEM format (RFC 7468).

Only supports public keys.

Warning: Private, invalid, incompatible or unparsable keys are silently ignored, without throwing an exception. This only throws an exception if no valid keys are found at all.

Usage

 import com.google.crypto.tink.PemKeyType;

 String pem = ...;
 PemKeyType type = ...;
 String pem2 = ...;
 PemKeyType type2 = ...;
 KeysetHandle handle = SignaturePemKeysetReader.newBuilder()
     .addPem(pem, type)
     .addPem(pem2, type2)
     .buildPublicKeysetHandle();
