Methods

Static compressPubkey

compressPubkey(pubkey: Uint8Array): Uint8Array

- Defined in crypto/src/secp256k1.ts:135
Takes a compressed or uncompressed pubkey and return a compressed one.

This function is idempotent.

Parameters
- pubkey: Uint8Array
Returns Uint8Array

Static createSignature

createSignature(messageHash: Uint8Array, privkey: Uint8Array): Promise<ExtendedSecp256k1Signature>

- Defined in crypto/src/secp256k1.ts:67
Creates a signature that is
- deterministic (RFC 6979)
- lowS signature
- DER encoded
Parameters
- messageHash: Uint8Array
- privkey: Uint8Array
Returns Promise<ExtendedSecp256k1Signature>

Static makeKeypair

makeKeypair(privkey: Uint8Array): Promise<Secp256k1Keypair>

- Defined in crypto/src/secp256k1.ts:31
Takes a 32 byte private key and returns a privkey/pubkey pair.

The resulting pubkey is uncompressed. For the use in Cosmos it should be compressed first using Secp256k1.compressPubkey.

Parameters
- privkey: Uint8Array
Returns Promise<Secp256k1Keypair>

Static recoverPubkey

recoverPubkey(signature: ExtendedSecp256k1Signature, messageHash: Uint8Array): Uint8Array

- Defined in crypto/src/secp256k1.ts:123
Parameters
- signature: ExtendedSecp256k1Signature
- messageHash: Uint8Array
Returns Uint8Array

Static trimRecoveryByte

trimRecoveryByte(signature: Uint8Array): Uint8Array

- Defined in crypto/src/secp256k1.ts:162
Parameters
- signature: Uint8Array
Returns Uint8Array

Static uncompressPubkey

uncompressPubkey(pubkey: Uint8Array): Uint8Array

- Defined in crypto/src/secp256k1.ts:151
Takes a compressed or uncompressed pubkey and returns an uncompressed one.

This function is idempotent.

Parameters
- pubkey: Uint8Array
Returns Uint8Array

Static verifySignature

verifySignature(signature: Secp256k1Signature, messageHash: Uint8Array, pubkey: Uint8Array): Promise<boolean>

- Defined in crypto/src/secp256k1.ts:89
Parameters
- signature: Secp256k1Signature
- messageHash: Uint8Array
- pubkey: Uint8Array
Returns Promise<boolean>
