# SecEncodeTransformCreate(_:_:)

Creates an encode transform object.

## Declaration

```swift
func SecEncodeTransformCreate(_ encodeType: CFTypeRef, _ error: UnsafeMutablePointer<Unmanaged<CFError>?>?) -> SecTransform?
```

## Parameters

- `encodeType`: The type of digest to compute. You may pass NULL for this parameter, in which case an appropriate algorithm will be chosen for you. See Encoding Types for a list of valid values.
- `error`: A pointer to a doc://com.apple.documentation/documentation/CoreFoundation/CFError. This pointer will be set if an error occurred. This value may be nil if you do not want an error returned.

## Return Value

Return Value A pointer to a new transform or NULL on error. In Objective-C, call the CFRelease function to free this object’s memory when you are done with it.

## Discussion

Discussion This function creates a transform which computes an encode.
