Properly proved. Has structure, has flavour, has a point.
Summary
Stunnel is a multiplatform GNU/GPL-licensed proxy that adds TLS encryption to existing clients and servers without requiring code changes. It uses OpenSSL for cryptography, supports various cryptographic algorithms, and can benefit from FIPS 140-2 validation. The tool is optimized for security, portability, scalability, and load-balancing, making it suitable for large deployments.
Key quotes
· 4 pulledStunnel is a proxy designed to add TLS encryption functionality to existing clients and servers without any changes in the programs' code.
Its architecture is optimized for security, portability, and scalability (including load-balancing), making it suitable for large deployments.
Stunnel uses the OpenSSL library for cryptography, so it supports whatever cryptographic algorithms are compiled into the library.
It can benefit from the FIPS 140-2 validation of the OpenSSL FIPS Provider, as long as the building process meets the OpenSSL FIPS 140-2 Security Policy.
