## Detailed Description

Member context interface.

## Function Documentation

EpidStatus EpidComputePreSig | ( | MemberCtx const * | ctx,
|  | PreComputedSignature * | precompsig
| ) |  |

Performs Pre-computation that can be used to speed up signing.

Warning
  Do not re-use the same pre-computed signature to generate more than one signature. If a pre-computed signature is used for computing two signatures, an attacker could learn the Intel(R) EPID private key.

Parameters

  [in] | ctx | The member context.
  [out] | precompsig | The pre-computed signature.

Returns
  EpidStatus
