SEC_E_CRYPTO_SYSTEM_INVALID
SEC_E_CRYPTO_SYSTEM_INVALID signals this condition: A required cryptographic system function or checksum capability was unavailable or invalid. The security package could not use a cryptographic component it required. This can be caused by damaged system components, unsupported algorithms, provider problems, or a system configuration that differs from the application assumptions.
What to check
- Capture the exact security package, algorithm, and operation that failed.
- Review Windows event logs for provider or certificate errors that occurred first.
- Use supported servicing and repair procedures; do not replace cryptographic libraries or registry settings with files copied from another computer.
