Public key cryptography is one of the fundamental technologies that enables the XRP Ledger and other blockchain systems to operate.
It uses a pair of keys: a public key and a private key. Anyone can create a new account and have authority to sign transactions from that account. In order to generate these keys, you can use a software library like ripple-keypairs.
Many of the applications that integrate with the XRP Ledger depend on the stability and security of ripple-keypairs in order to create and use XRP Ledger accounts.
Each account has an address, which is derived from the account's master public key. It might also have a regular key, which is a secondary way to authorize transactions from an account.
An account can also have a signing list to allow for multi-signing, which requires a transaction to have multiple signatures before it is considered valid.
We help to maintain and enhance the libraries underpinning the XRP Ledger in order to ensure superior security, safety and ease-of-use for every app that uses XRP.
High-quality apps deserve high-quality supporting libraries, and that's why we're excited to announce that ripple-keypairs v1.0 is now available.
Here are the library's main use cases:
- Generate new XRPL accounts (wallets)
- Generate a regular key to use with your account
- Generate keys to use for multi-signing
- Sign messages (create signatures)
- Verify messages (verify signatures)
- Generate a validator manifest public key
ripple-keypairs is fully open source and licensed under the ISC license, is available as an npm package and is easy to use in browser-based apps using a compiler like TypeScript, Browserify, Babel, or Parcel.
It is also an integrated component of ripple-lib (RippleAPI) and the RippleX Dev Kit, so if you're developing on the XRP Ledger, you are probably already using ripple-keypairs!
We continue to work with the open source XRP Community on the development of ripple-keypairs and the entire suite of XRPL libraries. We'd love to hear your feedback. You can reach out to us through GitHub issues.
As a responsible participant in the XRP Ledger ecosystem, Ripple is sponsoring a bug-bounty program to help encourage third-party reviews of the codebase. We urge developers and researchers to responsibly disclose any issues that they may find.
