+# KNOT & UNKNOT
+`knot` and `unknot` are simple bash script wrapper for 7zip.  
+Just wanted a quick (lazy) way to simple compress and encrypt a file or group of files. Who has time to remember more command arguments? XD
+Same process to uncompress/decrypt.  
+It uses AES256 (7zip default for .7f files), encrypt files headers to hide file structure and it deletes original files after completing the job.  
+
+
+## USE: knot
+`knot [file|folder|file1 file2 folder3...]`
+* Type output filename [first filename as default]
+* Type password, repeat.
+* Profit
+
+## USE: unknot
+`unknot [file.7z]`
+* Type your password
+* Profit
+
+## EXAMPLE
+
+$# `ls`  
+file1 file2 file3 folder1 folder2
+
+$# `knot file1 file3 folder2`  
+Output filename [file1]: myfiles  
+Enter your password: password@1  
+Repeat your password: password@1  
+
+$# `ls`  
+file2 folder1 myfiles.7z  
+
+$# `unknot myfiles.7z`  
+Enter your password: password@1  
+  
+$# `ls`  
+file1 file2 file3 folder1 folder2
