Returns the hex string result of SHA-2 family of hash functions (SHA-224, SHA-256, SHA-384, and SHA-512). The numBits indicates the desired bit length of the result, which must have a value of 224, 256, 384, 512, or 0 (which is equivalent to 256). Supports Spark Connect.
For the corresponding Databricks SQL function, see sha2 function.
Syntax
from pyspark.databricks.sql import functions as dbf
dbf.sha2(col=<col>, numBits=<numBits>)
Parameters
| Parameter | Type | Description |
|---|---|---|
col |
pyspark.sql.Column or str |
Target column to compute on. |
numBits |
int |
The desired bit length of the result, which must have a value of 224, 256, 384, 512, or 0 (which is equivalent to 256). |
Returns
pyspark.sql.Column: the column for computed results.
Examples
from pyspark.databricks.sql import functions as dbf
df = spark.createDataFrame([['Alice'], ['Bob']], ['name'])
df.select('*', dbf.sha2('name', 256)).show(truncate=False)
