The OpenSSL Toolkit
The OpenSSL Toolkit is an open source project that aims to provide a robust, commercial-grade, and full-featured toolkit for the Transport Layer Security (TLS) and Secure Sockets Layer (SSL) protocols. It also includes a general purpose cryptographic library called libcrypto. The OpenSSL Toolkit is used by many applications and websites to encrypt and authenticate data transmitted over the internet.
The SSL/TLS protocol
The SSL/TLS protocol is a standard protocol that enables secure communication between a client and a server over the internet. It uses encryption, authentication, and integrity checks to ensure that the data exchanged between the parties is confidential, authentic, and unaltered. The SSL/TLS protocol is widely used for web browsing, email, online banking, e-commerce, and other online services that require security and privacy.

FAQs
What is a DLL file?
A DLL file is a dynamic link library file that contains code, data, and resources that can be used by multiple programs. A DLL file can provide functionality, such as encryption, compression, or graphics, that can be shared by different programs without having to duplicate the code.
What is the difference between 32-bit and 64-bit Windows?
The difference between 32-bit and 64-bit Windows is the amount of memory that they can address. A 32-bit Windows system can address up to 4 GB of memory, while a 64-bit Windows system can address up to 128 GB of memory or more. A 64-bit Windows system can also run faster and more securely than a 32-bit Windows system.
How do I know if I have a 32-bit or a 64-bit Windows system?
To know if you have a 32-bit or a 64-bit Windows system, you can follow these steps:
Click on the Start button and type "system information" in the search box.
Click on the System Information app that appears in the results.
Look for the System Type entry in the System Summary section.
If it says "x86-based PC", you have a 32-bit Windows system. If it says "x64-based PC", you have a 64-bit Windows system.
How do I know if I need libssl-1_1.dll 64 bit or libssl-1_1.dll 32 bit?
