ABSTRACT:
In one embodiment, a mechanism for transport-safe codings for cryptographic use is disclosed. In one embodiment, a method for transport-safe coding for cryptographic use includes converting an input data stream into index values associated with “n” printable characters, wherein “n” is a radix associated with a base-“n” coding scheme and a prime power less than 94, performing a cryptographic operation on the index values to encrypt the index values, and translating the encrypted values directly into an output data stream of printable characters associated with the encrypted values in a base-“n” coding scheme.
