Question:

PGP makes use of the cipher feedback (CFB) mode of CAST-128, whereas most symmetric encryption applications (other than key encryption) use the cipher block chaining (CBC) mode.We have image text in transcribed

These two appear to provide equal security. Suggest a reason why PGP uses the CFB mode.
