```
from pyspark.context import SparkContext
from pyspark.sql import SparkSession
from awsgluedi.transforms import *

secret = "${SECRET}"
sc = SparkContext()
spark = SparkSession(sc)

input_df = spark.createDataFrame(
    [
        (1, "1234560000"),
        (2, "1234560001"),
        (3, "1234560002"),
        (4, "1234560003"),
        (5, "1234560004"),
        (6, "1234560005"),
        (7, "1234560006"),
        (8, "1234560007"),
        (9, "1234560008"),
        (10, "1234560009"),
    ],
    ["id", "phone"],
)

try:
    df_output = pii.CryptographicHash.apply(
        data_frame=input_df,
        spark_context=sc,
        source_columns=["id", "phone"],
        secret_id=secret,
        algorithm="HMAC_SHA256",
        output_format="BASE64",
    )
    df_output.show()
except:
    print("Unexpected Error happened ")
    raise
```

## Output
<a name="pyspark-CryptographicHash-output"></a>

A saída será:

```
```

 A transformação calcula os hashes criptográficos dos valores nas colunas “id” e “phone” usando o algoritmo e a chave secreta especificados e codifica os hashes no formato Base64. O DataFrame “df\$1output” resultante contém todas as colunas do DataFrame “input\$1df” original, além das colunas “id\$1hashed” e “phone\$1hashed” adicionais com os hashes computados.

 A transformação `CryptographicHash` aplica um algoritmo aos valores de hash na coluna. 
+ `source_columns`: uma matriz de colunas existentes.
+ `secret_id`: o ARN da chave secreta do Secrets Manager. A chave usada no algoritmo do prefixo do código de autenticação de mensagens por hash (HMAC) para hash das colunas de origem.
+ `secret_version`: opcional. O padrão é a versão mais recente do segredo.
+ `entity_type_filter`: matriz opcional de tipos de entidades. Pode ser usada para criptografar somente as PII detectadas na coluna de texto livre.
+ `create_secret_if_missing`: booleano opcional. Se verdadeiro, tentará criar o segredo em nome do chamador.
+ `algorithm`: o algoritmo usado para fazer o hash de seus dados. Valores de enumeração válidos: MD5, SHA1, SHA256, SHA512, HMAC\$1MD5, HMAC\$1SHA1, HMAC\$1SHA256, HMAC\$1SHA512.
