Cryptainer LE 6.1Description by Software Developer:
"Cryptainer LE is a freeware utility from Cypherix™. It is a 128 bit disk encryption software that is a miniature version of Cryptainer PE and Cryptainer. It creates encrypted containers (vaults) of up to 25 MB each to store any type of data. You can encrypt files and folders by simply dragging and dropping them into this vault. Additionally, it lets you create secure e-mail files that you can send to anyone.
Cryptainer LE includes a 'Mobile' feature, which allows it to encrypt all media (including, USB, CD ROM etc). It works on all 32 bit versions of Windows.
Cryptainer LE runs a 128 bit implementation of the Blowfish algorithm in Cipher Block Chaining (CBC) mode with a block size of 64 bytes.
CONFORMITY WITH STANDARDS.
Conforms to the following standards
SHA NIST FIPS
Key setting PKCS 5v2
HMAC RFC2104 HMAC test vectors RFC2202
IBS - ICS 36.080"
Note: Cryptainer comes in several editions - LE, PE, and SE. "Download" links to Cryptainer LE, which is freeware.
Cryptainer LE has a number of obvious downsides:
1. It only creates encrypted disks of up to 25 MB.
2. It employs only one encryption algorithm (Blowfish 128-bit).
Compare that to TrueCrypt
, which is also free.
