| Installation | |
| ------------ | |
| Copy both files to the following locations: |
| # Encryption functions. Requires the GNUpg "gpg" commandline tool. On OS X, "brew install gnupg" | |
| # Explanation of options here: | |
| # --symmetric - Don't public-key encrypt, just symmetrically encrypt in-place with a passphrase. | |
| # -z 9 - Compression level | |
| # --require-secmem - Require use of secured memory for operations. Bails otherwise. | |
| # cipher-algo, s2k-cipher-algo - The algorithm used for the secret key | |
| # digest-algo - The algorithm used to mangle the secret key | |
| # s2k-mode 3 - Enables multiple rounds of mangling to thwart brute-force attacks | |
| # s2k-count 65000000 - Mangles the passphrase this number of times. Takes over a second on modern hardware. | |
| # compress-algo BZIP2- Uses a high quality compression algorithm before encryption. BZIP2 is good but not compatible with PGP proper, FYI. |
| # compile | |
| $ g++ zlib-example.cpp -lz -o zlib-example | |
| # run | |
| $ ./zlib-example | |
| Uncompressed size is: 36 | |
