CRYPT_HASH()
Доступно в
DSQL, PSQL
Синтаксис
CRYPT_HASH (value USING <algorithm>)
<algorithm> ::= { MD5 | SHA1 | SHA256 | SHA512 | SHA3_224 | SHA3_256 | SHA3_384 | SHA3_512 }
| Параметр | Описание |
|---|---|
value |
Выражение любого типа. Не строковые и не бинарные типы приводятся к строке. |
algorithm |
Алгоритм хеширования. |
Тип возвращаемого результата
VARBINARY
Функция CRYPT_HASH возвращает криптографический хэш входной строки, используя указанный алгоритм.Эта функция полностью поддерживает текстовые BLOB любой длины и с любым набором символов.Предложение USING позволяет указать алгоритм по которому вычисляет хэш.
