Open Source Cryptography

Providing open source cryptography & transport libraries

What is open source cryptography at AWS?

Cryptography is at the heart of AWS, underpinning security for both AWS and its customers. It's seamlessly integrated into the operations we perform, enabling the secure storage and transmission of your data. AWS is dedicated to offering security-focused services and tools that promote best practices in cryptography. As part of this commitment, AWS is proud to contribute our reliable, high-performance cryptographic and transport libraries to the open source community.

In 2015, AWS introduced s2n-tls, a fast open source implementation of the TLS protocol. The name "s2n", or "signal to noise," refers to the way encryption masks meaningful signals behind a facade of seemingly random noise. Since then, AWS has launched several other open source cryptographic libraries, including Amazon Corretto Crypto Provider (ACCP) and AWS Libcrypto (AWS-LC). AWS believes that open source benefits everyone, and we are committed to expanding our cryptographic and transport libraries to meet the evolving security needs of our customers.

Federal Information Processing Standard 140-3

The Federal Information Processing Standard (FIPS) 140-3 is a rigorous technical standard for cryptographic modules used by the U.S. and Canadian Federal governments. AWS is proud that the National Institute of Standards and Technology (NIST) has awarded AWS-LC a FIPS 140-3 level 1 validation certificate. AWS customers may leverage AWS-LC and our other open source libraries to help meet security goals.
