Top 7 constant-time Open-Source Projects
-
If you want some random string (e.g. for a random filename), you can use bin2hex(random_bytes(16)). This will generate a random 128 bit identifier using the CSPRNG. To be extra safe, use https://github.com/paragonie/constant_time_encoding instead of bin2hex. The constant time encoder prevents some additional (more obscure) attacks.

constantine
Constantine: modular, high-performance, zero-dependency cryptography stack for proof systems and blockchain protocols.

InfluxDB
Power Real-Time Data Analytics at Scale. Get real-time insights from all types of time series data with InfluxDB. Ingest, query, and analyze billions of data points in real-time with unbounded cardinality.

o1heap
Constant-complexity deterministic memory allocator (heap) for hard real-time high-integrity embedded systems. There is very little activity because the project is finished and does not require further changes.
-
recrypt
A set of cryptographic primitives for building a multi-hop Proxy Re-encryption scheme, known as Transform Encryption. (by IronCoreLabs)

WorkOS
The modern identity platform for B2B SaaS. The APIs are flexible and easy-to-use, supporting authentication, user identity, and complex enterprise features like SSO and SCIM provisioning.
