README for PassLok Github page

PassLok is a privacy app that implements public key cryptography functions on a browser.

These are the principles guiding the design of PassLok:
o	Perfect portability. Runs on any computer or mobile device.
o	Completely self-contained so it runs offline. No servers.
o	Nothing should be installed. No required secrets saved.
o	Highest-level security at every step. No compromises.
o	Easy to understand and use by novices. Graphical interface,
	as clean and simple as possible. No cryptographic jargon.

Because of this, PassLok is pure html code consisting mostly of javascript instructions. Its cryptography code is based on the SJCL code, also on Github. It uses AES for symmetric encryption and elliptic curves (NIST-521 curve) for the public-key functions.

PassLok was started as URSA, also by F. Ruiz, and developed privately up to version 1.3.03, made on 8/15/13. Commits on Github begin seriously with this version.

Cryptography Notice

  This distribution includes cryptographic software. The country in
  which you currently reside may have restrictions on the import,
  possession, use, and/or re-export to another country, of encryption
  software. BEFORE using any encryption software, please check your
  country's laws, regulations and policies concerning the import,

  The U.S. Government Department of Commerce, Bureau of Industry and
  Security (BIS), has classified this software as Export Commodity
  Control Number (ECCN) 5D002.C.1, which includes information security
  software using or performing cryptographic functions with asymmetric
  algorithms. The form and manner of this distribution makes it
  eligible for export under the License Exception ENC Technology
  Software Unrestricted (TSU) exception (see the BIS Export
  Administration Regulations, Section 740.13) for both object code and
  source code.
