Abstract: Embodiments are provided herein for applying adaptive encryption in checkpoint recovery of a file transfer. An embodiment includes establishing a first connection between a first node and a second node, generating a first ciphertext object at the second node by encrypting first input data received from the first node based, at least in part, on an encryption algorithm and an input block, and storing the first ciphertext object in an output file. The embodiment further includes, subsequent to a communication failure via the first connection, establishing a second connection between the first node and the second node, obtaining a last block stored in the output file, and generating a second ciphertext object by encrypting second input data received from the first node based, at least in part, on the encryption algorithm and the last block. More specific embodiments include storing a current file offset based on detecting the communication failure.
