I would need to crypt some source code ( C, FORTRAN) in order to make
him humanly unreadable but still comprensible for such compilers. The
decoding scheme would take place on the fly when compilation is needed
but not from a human intervention. Thanks for any information !

[Gimpel Software at least used to have a program called "C shroud" which
obfuscated C source code so that it was nearly incomprehensible to humans
while still semantically equivalent to the original. It turned all the
flow of control into gotos, changed all the variable names into random
strings, stuff like that. Another approach is ANDF which is essentially
tokenized C, although it appears that it's possible to recover something
pretty close to the original source with de-ANDF-ing tools. -John]
