cenc

cenc (camellia encrypt) - stupid simple file encryption written in pure C

Ussage

Note: You can choose any file extension you like. If you use the same name for both the input file and the output file, the original file will be overwritten. For example, if a file is named test.pdf, you could choose test.pdf.whatever or test.pdf.crypt as the output file.

Encryption:

cenc -e -i inputfile -o outputfile

Example:

cenc -e -i test.pdf -o test.pdf.crypt

Decryption:

cenc -d -i inputfile -o outputfile

Example:

cenc -d -i test.pdf.crypt -o test.pdf
