Methods
(static) assert_ripemd160(data, ripe)
to assert if source data is consisted with Ripemd160.
Example
import { assert_ripemd160 } from "ultrain-ts-lib/src/crypto";Parameters:
| Name | Type | Description |
|---|---|---|
data |
source data to assert. |
|
ripe |
encrypte algorithm. |
(static) assert_sha1(data, sha1)
to assert if source data is consisted with SHA1.
Example
import { assert_sha1 } from "ultrain-ts-lib/src/crypto";Parameters:
| Name | Type | Description |
|---|---|---|
data |
source data to assert. |
|
sha1 |
encrypte algorithm. |
(static) assert_sha256(data, sha256)
to assert if source data is consisted with SHA256.
Example
import { assert_sha256 } from "ultrain-ts-lib/src/crypto";Parameters:
| Name | Type | Description |

(static) assert_sha512(data, sha512)
to assert if source data is consisted with SHA512.
Example
import { assert_sha512 } from "ultrain-ts-lib/src/crypto";Parameters:
| Name | Type | Description |
|---|---|---|
data |

encrypte algorithm. |
(static) get_random_number(code, table, scope, primary)
Get a random number from system service. This number will be kept the same during a consensus period, so, if you invoke this function multi times in an action, the random number wouldn't change.
Example
import { get_random_number } from "ultrain-ts-lib/src/crypto";Parameters:
| Name | Type | Description |
|---|---|---|
code |
account_name | system service account. |
table |
u64 | table name of the random number. |
scope |
u64 | scope of the random number. |
primary |
u64 | primary of the random number. |
(static) verify_with_pk(pk_str, pk_proof, message)
to verity pk and proof.
Example
import { verify_with_pk } from "ultrain-ts-lib/src/crypto";Parameters:
| Name | Type | Description |
|---|---|---|
pk_str |
string of pk |
|
pk_proof |
string of proof |
|
message |
a message |
fromString(hexStr)
hex string to crypto.
Parameters:
| Name | Type | Description |
|---|---|---|
hexStr |
a hex string. |
toString()
crypto result to hex string.
