A scanned FIPS 140-2 Validation Certificate document is available for download on the NIST web page. It can benefit from the FIPS 140-2 validation of the OpenSSL FIPS Object Module, as long as the building process meets its Security Policy. Stunnel uses the OpenSSL library for cryptography, so it supports whatever cryptographic algorithms are compiled into the library. Its architecture is optimized for security, portability, and scalability (including load-balancing), making it suitable for large deployments. Functionality to existing clients and servers without any changes in the programs’ code.
