[Chicago] encrypting 5gb files?

In CRC mode, if the plaintext is long, brute force attacks become unfeasible, even if the encryption algorithm is fast. Even for encryption algorithms, speed should be considered a plus, not a minus.

In general speed is the enemy of security in encryption. The faster you can encrypt/decrypt the file, the faster someone can crack it.

What I'm trying to do is create backup files on amazon S3 servers
which allow you to upload up to 5bg per files. Since the data I'm
uploading is very sensitive I want to encrypt the files.
I'm looking for a algorithm or a tool that would allow me to
encrypt/decrypt the file at a reasonable speed and goods security.
Let me know,
