Problem summary

  • The customer has observed that the KeyPairGenerator of the
    IBMPKCS11Impl provider throws the following exception when asked
    to generate a key pair of size 2048.
    InvalidParameterException: Key size must be a multiple of 64 and
    at most 1024 bit
    

Problem conclusion

  • This defect will be fixed in:
    7.0.0 SR2
    6.0.0 SR11
    5.0.0 SR14
    .
    The latest PKCS#11 spec (version 2.3)
    and the associated FIPS publication
    186-2 have no awareness of DSA key sizes
    greater than 1024.  For that reason,
    the IBMPKCS1Impl provider cannot
    support DSA keys > 1024.
    Additional defensive code has been added to the
    "key generation" and "key translation" logic of the
    IBMPKCS11Impl provider to throw more descriptive exceptions
    when the caller attempts to use a DSA key size > 1024.
    

Temporary fix
