What does Intel IPP status 25 (ippStsInsufficientEntropy) mean?

Status / error code:		Category:

Constant name:
Source:		Operating System:
Description: IPP could not generate a prime or key because the supplied random material lacked entropy.

ippStsInsufficientEntropy

This status belongs to cryptographic key or prime generation. The operation received seed or stimulus data, but IPP determined that it was not sufficient for the requested prime/key generation process.

It is a security-relevant status: retrying with the same deterministic seed does not improve the result.

Diagnostic focus

Check the source of random seed material and whether it is approved for cryptographic use.
Verify that test vectors and deterministic modes are not accidentally used in production key generation.
Log only metadata about entropy sources; do not log seed or private-key material.
