Open-source cryptographic libraries

Open-source cryptographic libraries are collections of code that enable secure data encryption and decryption, made freely available for anyone to review, use, and modify. They help protect sensitive information, such as emails and transactions, by applying complex mathematical techniques to keep data private and verify identities. Because the code is open, it can be scrutinized for security flaws, fostering trust and improvements from the global community. Examples include libraries like OpenSSL and Libsodium, which are widely used in securing internet communications and applications.
