secp256r1

Previoussecp256k1NextIdentities

Last updated 12 days ago

The most commonly used and well-supported Elliptic Curve is NIST P-256. This is an ECDSA method using the secp256r1 curve.

Seeding

LTO libraries use BIP39 with the English word list to create a seed phrase for the secp256k1 key type. BIP32 is used to generate the binary seed from the seed phrase.

BIP39 + BIP32 with secp256r1 is non-standard and not supported by mainstream wallets. It is safe when using hardened paths, but specific to LTO Network.

Signing

  • Created private key using the account seed 93d...S1v.

  • Create the corresponding coordinates for the public key and compress the public key.

Encryption

Encryption is done using , which combines ECDSA with AES. It uses the same keys for encryption and signing.
