bool DL_PrivateKeyImpl< DL_GroupParameters_EC< EC > >::Validate | ( | RandomNumberGenerator & | rng, | |

check this object for errors
level | denotes the level of thoroughness: 0 - using this object won't cause a crash or exception (rng is ignored) 1 - this object will probably function (encrypt, sign, etc.) correctly (but may not check for weak keys and such) 2 - make sure this object will function correctly, and do reasonable security checks 3 - do checks that may take a long time |

void DL_PrivateKeyImpl< DL_GroupParameters_EC< EC > >::Precompute | ( | unsigned int | precomputationStorage = 16 |

do precomputation
The exact semantics of Precompute() is varies, but typically it means calculate a table of n objects that can be used later to speed up computation.

this may be useful if DEREncode() would be too inefficient
