Problem summary


    

  • The PKCS11KeyStore.doesPublicKeyMatchPrivateKey( ) method within
the IBMPKCS11Impl provider uses SHA1xxxxx signature mechanisms
to match private and public HSM keys. SHA1xxxxx signature
mechanisms are not available when a Luna 7 HSM is configured to
operate in FIPS mode.

    



Problem conclusion


    

  • The PKCS11KeyStore.doesPublicKeyMatchPrivateKey( ) method has
been updated to use the signature algorithms below instead to
match private and public keys for the following key types:
RSA => SHA256withRSA
DSA => SHA256wthDSA
EC   => SHA256withECDSA
