I know you loved him. I tried to tell him so, but he wouldn’t listen. So cruel to put the hammer within your reach, knowing that you could never lift it. The burden of the throne has fallen to me now.
What is heimdal?
heimdal builds on Neon, a Rust-Node bridge and rust-crypto, a safe, pure-Rust cryptography library. The goal is to provide safety and performance to developers while maintaining a high level of usability on all supported architectures.
- Heimdal consists of only three direct components - a PRNG as entropy source, the business logic and Neon for integration with Node.
- Rust builds an object file from heimdal and links it to the Node-ABI-specific V8 abstraction layer provided by Neon, finally producing a native Node module.
- Upon build, the test-suite is executed against the binary, verifying the integrity of the crypto functions and mitigating potential issues caused by unsafe compiler optimisations.
If you're reading this, heimdal may be still too raw for you. However, if you have a nightly Rust toolchain installed, just run
npm i. This will kickoff the build and test suite.
'use strict'; const heimdal = require('heimdal');
Example usage for Ed25519
'use strict'; const assert = require('assert'); const heimdal = require('heimdal'); const ed25519 = new heimdal.Ed25519(); const alice = ed25519.keypair(); const bob = ed25519.keypair(); const aliceSharedSecret = ed25519.exchange(alice.public, bob.private); const bobSharedSecret = ed25519.exchange(bob.public, alice.private); assert(0 === Buffer.compare(aliceSharedSecret, bobSharedSecret)); const message = new Buffer([ 0x49, 0x74, 0x27, 0x73, 0x20, 0x61, 0x62, 0x6f, 0x75, 0x74, 0x20, 0x68, 0x6f, 0x77, 0x20, 0x68, 0x61, 0x72, 0x64, 0x20, 0x79, 0x6f, 0x75, 0x20, 0x63, 0x61, 0x6e, 0x20, 0x67, 0x65, 0x74, 0x20, 0x68, 0x69, 0x74, 0x20, 0x61, 0x6e, 0x64, 0x20, 0x6b, 0x65, 0x65, 0x70, 0x20, 0x6d, 0x6f, 0x76, 0x69, 0x6e, 0x67, 0x20, 0x66, 0x6f, 0x72, 0x77, 0x61, 0x72, 0x64, 0x3b, 0x0a, 0x68, 0x6f, 0x77, 0x20, 0x6d, 0x75, 0x63, 0x68, 0x20, 0x79, 0x6f, 0x75, 0x20, 0x63, 0x61, 0x6e, 0x20, 0x74, 0x61, 0x6b, 0x65, 0x20, 0x61, 0x6e, 0x64, 0x20, 0x6b, 0x65, 0x65, 0x70, 0x20, 0x6d, 0x6f, 0x76, 0x69, 0x6e, 0x67, 0x20, 0x66, 0x6f, 0x72, 0x77, 0x61, 0x72, 0x64, 0x2e, 0x0a, 0x54, 0x68, 0x61, 0x74, 0x27, 0x73, 0x20, 0x68, 0x6f, 0x77, 0x20, 0x77, 0x69, 0x6e, 0x6e, 0x69, 0x6e, 0x67, 0x20, 0x69, 0x73, 0x20, 0x64, 0x6f, 0x6e, 0x65, 0x21 ]); console.log('Message:\n\n%s\n', message.toString()); const aliceSignature = ed25519.signature(message, alice.private); console.log('Alice signature: ', aliceSignature); const bobVerification = ed25519.verify(message, alice.public, aliceSignature); console.log('Bob verification: %s', bobVerification);
