Transmute DID

🚧 Under Construction. Not for production use! 🚧

Decentralized Identifiers (DIDs) are a new type of identifier for verifiable, "self-sovereign" digital identity. DIDs are fully under the control of the DID subject, independent from any centralized registry, identity provider, or certificate authority. DIDs are URLs that relate a DID subject to means for trustable interactions with that subject. DIDs resolve to DID Documents — simple documents that describe how to use that specific DID. Each DID Document contains at least three things: cryptographic material, authentication suites, and service endpoints. Cryptographic material combined with authentication suites provide a set of mechanisms to authenticate as the DID subject (e.g., public keys, pseudonymous biometric protocols, etc.). Service endpoints enable trusted interactions with the DID subject.

What it does

The transmute-did package contains several libraries for basic cryptographic operations

src/lib/ethereumExtensions/: Ethereum

Creating an Ethereum identity

• Generate a BIP-39 Mnemonic
• Get a keypair from a mnemonic and a derivation path
• Get an Ethereum address from a public key

src/lib/openpgpExtensions/: PGP

PGP uses RSA by default but also supports the following Elliptic Curves: curve25519, p256, p384, p521, secp256k1, brainpoolP256r1, brainpoolP384r1, brainpoolP512r1.

This library provides:

• generation of PGP keypairs from a name and a passphrase
• Signing a message with the sender's private key
• Verifying a message with the sender's public key
• Encrypting a message with the recipient's public key and signing it with the sender's private key
• Decrypting a message with the recipient's private key and verifying it with the sender's public key

src/lib/sodiumExtensions/: Libsodium

LibSodium uses ED25519 by default.

This library provides:

• a Signature scheme using libsodium's crypto_sign
• a Public-key authenticated encryption scheme using libsodium's crypto_box

src/lib/shamirExtensions/: Secret Sharing

This library provides

• Shamir secret sharing methods

src/lib/misc/: Miscellaneous tools

This library provides

• Transmute DID document generation
• converting keypairs to a ciphertext wallet
