CRYPTO_LIBRARY_INTERNAL_ERROR
Cryptographic library internal failure
CRYPTO_LIBRARY_INTERNAL_ERROR is bug check code 0x00000171. The built-in table identifies it as CRYPTO_LIBRARY_INTERNAL_ERROR
; the useful diagnostic question is what Windows component raised the stop and which invariant failed.
This bug check is about internal state in the kernel cryptographic library or a closely related kernel crypto component. It is not simply a certificate validation failure or a user-mode TLS error.
How to read the parameters
- The arguments and stack identify which internal crypto path failed.
- The failure can occur in boot, integrity, key, algorithm, or security-feature code paths.
- Treat it as a kernel component failure until the dump names a third-party filter or driver.
What to check in the dump
- Collect the full stack, loaded crypto/security modules, recent updates, and boot-integrity configuration.
- Look for security products, storage encryption, boot encryption, and kernel filters that hook or depend on crypto services.
- Compare with CRYPTO_SELF_TEST_FAILURE when the evidence points to a self-test rather than general internal state.
