continuous fuzzing for open source software. Fuzz testing is a well-known technique for uncovering programming errors in software. Many of these detectable errors, like buffer overflow, can have serious security implications. Google has found thousands of security vulnerabilities and stability bugs by deploying guided in-process fuzzing of Chrome components, and we now want to share that service with the open source community.
Securing open-source package ecosystems by originating, validating, and augmenting build attestations.
OSS Rebuild aims to apply reproducible build concepts at low-cost and high-scale for open-source package ecosystems.
Rebuilds are derived by analyzing the published metadata and artifacts and are evaluated against the upstream package versions. When successful, build attestations are published for the upstream artifacts, verifying the integrity of the upstream artifact and eliminating many possible sources of compromise.

One-Time-Secret sharing platform with a symmetric 256bit AES encryption in the browser
ots is a one-time-secret sharing platform. The secret is encrypted with a symmetric 256bit AES encryption in the browser before being sent to the server. Afterwards an URL containing the ID of the secret and the password is generated. The password is never sent to the server so the server will never be able to decrypt the secrets it delivers with a reasonable effort. Also the secret is immediately deleted on the first read.
Otter is designed to provide an excellent developer experience while maintaining blazing-fast performance. It aims to address the shortcomings of its predecessors and incorporates design principles from high-performance libraries in other languages (such as Caffeine).
