toIotaAddress()

toIotaAddress(): string

Defined in: sdk/typescript/src/cryptography/keypair.ts:85

Returns

string

---

signingDigest()

static signingDigest(bytes, intent): Uint8Array

Defined in: sdk/typescript/src/cryptography/keypair.ts:40

Sign messages with a specific intent. By combining the message bytes with the intent before hashing. Returns the digest.

Parameters

bytes

Uint8Array

intent

IntentScope

Returns

Uint8Array
