encrypt is a simple yet powerful file encryption application, and is available not only for Android devices but desktops and laptops too. By having a simple and intuitive interface it achieves a similar look and feel on any system, allowing the user to get right down to securing their data.
At its core it uses free libraries to provide a large collection of algorithms to choose from, many of which were finalists for the AES competition.
The following cryptographic algorithms are currently supported on both desktop and Android systems: AES (and other Rijndael variants up to 256 bits), Serpent (128, 192 and 256 bit variants), Blowfish (128 bit) and Twofish (128 and 256 bits), as well as (Triple) DES.
And the following one-way hash algorithms are common to all systems: TIGER, SHA1, the SHA2 variants (256, 384 and 512 bits), and MD5.
In an effort to make encrypt even more useful to even more people, it's been written to use the compatible encryption libraries by the GNU Project: libgcrypt and gnu-crypto. This allows many different algorithms to be chosen from on both Android devices and desktop systems.
The permissions requested are WRITE_EXTERNAL_STORAGE, obviously you need this if you want to encrypt/decrypt files stored on your SD-card; and READ_PHONE_STATE, which isn't as obvious, but comes down to supporting Cupcake devices :-)
