Static functions
#crypto.SHA512.digest
function crypto.SHA512.digest(message: string, as_hex?: boolean): stringComputes the SHA512 digest of the given input string.
This static method takes a string and returns its SHA512 hash as a hexadecimal string. Commonly used for checksums, data integrity validation, and password hashing.
| Name | Type | Description |
|---|---|---|
message | string | The message to compute SHA512 for. |
as_hexoptional | boolean | If true, the result will be a hex string. |
| Type | Name | Description |
|---|---|---|
string | str_result | The SHA512 string of the message. |
Methods
digest | Calculates the SHA512 digest based on the current state or input of the object. |
reset | Resets the SHA512 object to its initial state. |
update | Updates the SHA512 object with the given string. |
#SHA512:digest
function crypto.SHA512:digest(as_hex?: boolean): stringCalculates the SHA512 digest based on the current state or input of the object.
This instance method returns the SHA512 hash of the data associated with the object. Useful when the SHA512 object has been incrementally updated with input data.
Does not change the state, so the object can be updated further.
