301 | HEH is a proposed block cipher mode of operation which extends the | |
302 | strong pseudo-random permutation (SPRP) property of block ciphers to | |
303 | arbitrary-length input strings. This provides a stronger notion of | |
304 | security than existing block cipher modes of operation (e.g. CBC, CTR, | |
305 | XTS), though it is usually less performant. Applications include disk | |
306 | encryption and encryption of file names and contents. Currently, this | |
307 | implementation only provides a symmetric cipher interface, so it can't | |
308 | yet be used as an AEAD. | |
