Coherence’s objective is to improve security in L7 with modern cryptography.
Coherence (ko.eˈɾen.s) performs and offloads cryptography operations with a focus on interoperability, flexibility and simplicity. Coherence gives an interface for modern cryptographic algorithms which is inspired by Openssl, it is a REST API in order to be used by any language, in other words Coherence minimizes development time and code complexity. Some of the algorithms offered by Coherence are AES and AES candidates, Sosemanuk, SHA* family, HMAC, DH, RSA, DSA, ECC, NTRU.
There is a couple of good reasons to use Coherence:
    Offload, you have an specialized software dedicated entirely for cryptographic operations. Cryptographic operations like encrypting and decrypting is a very CPU-intensive task for webapps, so offload alleviates CPU-intensive encryption and decryption tasks from your webapp, boosting application performance.
    Interoperability, it doesn’t depend on a language programming, it depends on standards HTTP/GRPC and JSON, so you can integrate with homogeneous and heterogeneous systems.
    Flexibility, it gives you a complete cryptographic toolkit to implement stream ciphers, block ciphers, RSA, Elliptic curves, Post quantum cryptography. So it gives you all that you need to create your own cryptographic protocol.
    Open source, you can inspect, modify, and enhance.
    Free of charges, you don’t have to pay.
