LEACrypt
TTAK.KO-12.0223 Lightweight Encryption Algorithm Tool
The Lightweight Encryption Algorithm (also known as LEA) is a 128-bit block cipher developed by South Korea in 2013 to provide confidentiality in high-speed environments such as big data and cloud computing, as well as lightweight environments such as IoT devices and mobile devices. LEA is one of the cryptographic algorithms approved by the Korean Cryptographic Module Validation Program (KCMVP) and is the national standard of Republic of Korea (KS X 3246). -

TraySafe
Elegant and reliable profile data storage
...PIN functionality is included in versions 1.1.0 and above. The serious perk of the app is that all the info is saved as encrypted data in the data.tsf file in the program directory. The simple yet effective encryption algorithm has a password hash, salt key and vigenère cipher key that are changed with every update. The only thing you have to do when updating is to delete the .tsf files and re-enter all your info again so that it can be encrypted using the new parameters. Detailed How-To can be found in the project wiki. -

MOTE CSPRNG & Stream Cipher
A family of small-state CSPRNGs and Stream Ciphers
MOTE is a fast, small-state, cryptographically secure pseudo-random number generator (CSPRNG) and stream cipher. MOTE exhibits uniform distribution, mixes extremely rapidly, has no detected bias, and comes in three variants: MOTE8, with an internal state array of 8+4 32-bit words; MOTE16, with an internal state of 16+4 words; and MOTE32 with a 32+4-word state. The former permit seeding with a key of up to 256 or 512 bits, the latter with a 1024-bit key. Reduced to essentials, MOTE is only... -

BEDBUG CSPRNG & Stream Cipher
A family of FLEA-inspired CSPRNGs and Stream Ciphers
BEDBUG is a small, fast, cryptographically secure pseudo-random number generator (CSPRNG) and stream cipher. It exhibits uniform distribution, mixes rapidly (with worst-case avalanche better than 16-bits), has no detected bias, and comes in three variants: BEDBUG128, with an internal state array of 128+3 32-bit words; BEDBUG256, with an internal state of 256+3 words; and BEDBUG512 with a 512+3-word state. The former permit seeding with a key of up to 4096 or 8192 bits, the latter with a... -

SES Super-Encypherment Scrambler
SES brings back the uncrackable onetime pad, with a digital twist.
SES brings back the uncrackable onetime pad, with a digital twist. It is well known that a random key of message-length is the only provably unbreakable cipher. SES uses cryptographic strength pseudo-random keys of message-length for its many encipherments, in addition to offering true one-time pad capability for the intrepid. SES is built on ISAAC, Bob Jenkins' unbroken CSPRNG, a fast and simple stream cipher placed in the Public Domain in 1996. SES now gives you the ability to... -

ISC - The ISAAC Stream Cipher
ISC lets you encrypt & decrypt text and files of any type up to 4GB
ISAAC is a cryptographically secure pseudo-random number generator (CSPRNG) and stream cipher. It was developed by Bob Jenkins from 1993-1996 and placed in the Public Domain. ISAAC is fast - especially when optimised - and portable to most architectures in nearly all programming and scripting languages. After more than 20 years of existence ISAAC has not been broken, and the little program you have here allows you to use it to encrypt and decrypt text of arbitrary length, files of any type, on a key-phrase of any complexity. ... -

MLCrypt
Simple, lightweight, standalone command-line single file encryption.
Simple, lightweight, cross-platform (Windows / Linux / ARM6 Linux), cross-arch (x32 / x64), standalone command line file encryption program. GnuPG is probably the best application for cross-platform encryption. However, its usage on Windows PCs may be inconvenient (installation administrator rights; large executable size for perhaps just a one-time file decryption, complicated command-line switches for stronger encryption). NCrypt would fulfill this task, but does not operate on 64-bit... -
