Since this is a new program, it may be flagged as unsafe by your antivirus software. If so, select 'View Details' and 'Trust' in your security options.

This program (as with all Skylark software) does not need to be installed, so it can be simply copied to a memory stick and run from there.
For added security, run the program while disconnected from all networks and from the Internet.

SkylarkCrypt does not use the registry, instead it creates a simple preferences file in the same folder in which it was run.
An encrypted version of your Salt is saved in the preferences file, but your password is never saved, so make sure to remember your password.
You should save a copy of your Salt preferably in an offline memory stick.

SkylarkCrypt uses AES (CFB) 128 bit encryption (re Vincent Rijmen and Joan Daemen, via Apache License 2.0, see with salted and hashed passwords with an optional user specific 32 character salt value. It can encrypt and decrypt any file, but is specifically useful to edit and save secure text in an encypted text file.
It also contains some useful utilities such as generating a hash of a file or password, creating 81 tryte IOTA keys, etc.

Recent changes:
Beta version 0.91 improves prompts to save edited text when closing, and adds more 'How To' help text.

SkylarkCrypt will keep you informed about the strength of your passwords, including warning against commonly used text strings.

Normal disclaimer: We do not warrant that this program works or will not fail or that the encryption will not eventually be cracked, or that it won't crash and lose your data, so please keep an offline backup of all your important data.

Most especially, do not forget your password and keep a copy of your salt value!

To open your encrypted files on a new computer you will need your password and to paste your original Salt value into the new PC.

SkylarkCrypt normally salts and hashes passwords for brute force safe encryption, but very strong passwords can be used directly if needed.
