i guessed 128-bit AES. not too far off. ;)

AES is my personal favourite, i think.

"For technically savvy users, here are some details on how Jungle Disk
encrypts your files.
Jungle Disk encrypts files that are stored on S3 prior to uploading them
using 256-bit AES. AES is an industry (and government) standard and is
one of the most well studied and most secure encryption algorithms
available. Jungle Disk uses a unique key for each file, and constructs
the key using a HMAC that helps protect against certain attacks. Code
that demonstrates how data is encrypted/decrypted is available for
download on the Jungle Disk Download page under the GPL license.
Jungle Disk adds a special metadata header to each file when it is
uploaded. The header identifies the type of encryption used and contains
a salt value and a one-way hash of the salted key. This allows Jungle
Disk to determine the correct key to use to decrypt the file. Note that
without the decryption keys the header is of no use, and you cannot even
tell which files are encrypted with which keys unless you possess the keys."
