SecEncodeTransformCreate(_:_:)

Declaration

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 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

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

This function creates a transform which computes an encode.
