Class DecryptRaw

java.lang.Object
dev.frostlake.functions.BuiltInFunction
dev.frostlake.functions.scalar.crypto.DecryptRaw
public class DecryptRaw extends BuiltInFunction
DECRYPT_RAW(value, key, iv [, additional_authenticated_data [, encryption_method [, aead_tag]]]) — reverses EncryptRaw. The optionals nest from the LEFT (live-measured): the fourth argument is ALWAYS the AAD, the fifth the method, and the AEAD tag sits strictly SIXTH — a four-argument call putting the tag fourth fails "Decryption mode requires an AEAD tag as parameter", exactly as any GCM call that never reaches the sixth argument does, and a sixth argument of the wrong length fails "Wrong AEAD tag size. Expected 16, but got N" (both messages verbatim). All BINARY arguments are hex strings; the returned decrypted value is BINARY (hex). Only AES-GCM is supported. A wrong key, IV, AAD or tag fails authentication and raises, exactly as Snowflake's GCM verification does.

    • evaluate

      public Object evaluate(List<Object> args)
      Description copied from class: BuiltInFunction
      Computes the function's result over its already-evaluated argument values. A SQL NULL argument arrives as Java null, and returning null makes the SQL result NULL.
      Specified by:
      evaluate in class BuiltInFunction
      Parameters:
      args - the argument values, in call order
      Returns:
      the function's value for these arguments, or null for SQL NULL

    • getMinArgCount

      public int getMinArgCount()
      Description copied from class: BuiltInFunction
      The fewest arguments a call to this function may pass; fewer is an argument-count error.
      Specified by:
      getMinArgCount in class BuiltInFunction
      Returns:
      the minimum accepted argument count

    • getMaxArgCount

      public int getMaxArgCount()
      Description copied from class: BuiltInFunction
      The most arguments a call to this function may pass; Integer.MAX_VALUE marks a variadic function (see BuiltInFunction.isVariadic()).
      Specified by:
      getMaxArgCount in class BuiltInFunction
      Returns:
      the maximum accepted argument count
