## computeBinaryTransactionHash
|
|
|
|
`computeBinaryTransactionHash(txBlobHex: string): string`
|
|
|
|
Returns the hash (id) of a binary transaction blob.
|
|
|
|
This is a static method on the `RippleAPI` class.
|
|
|
|
### Parameters
|
|
|
|
This method takes one parameter, a string containing a binary transaction in hex.
|
|
|
|
### Return Value
|
|
|
|
This method returns a string representing the transaction's id (hash).
|
|
|
|
### Example
|
|
|
|
```javascript
|
|
const signed_blob = '120000228000000024000B2E5A201B0066374B61400000003B9ACA0068400000000000000C732102356E89059A75438887F9FEE2056A2890DB82A68353BE9C0C0C8F89C0018B37FC74473045022100B3721EEB1ED6DFF29FB8B209E2DE6B54A0A6E44D52D926342F3D334BE98F08640220367A74107AD5DEAEFA3AB2984C161FC23F30B2704BB5CC984358BA262177A4568114F667B0CA50CC7709A220B0561B85E53A48461FA883142B71D8B09B4EE8DAA68FB936C23E3A974713BDAC'
|
|
if (typeof signed_blob === 'string' && signed_blob.match(/^[A-F0-9]+$/)) {
|
|
const id = RippleAPI.computeBinaryTransactionHash(signed_blob)
|
|
console.log('Transaction hash:', id')
|
|
}
|
|
```
