This JavaScript library provides encryption using simple, text-oriented method called column transposition. The idea is to write the plain text in block on the row-first bases. The text is then read column-first. The trick is in that the columns are not read from left to right, but in the order specified by the encryption key. Transliteration is also used.
Instructions:
Input the password into the password field.
Optionally, input the signature into the signature field:
Input the plain text into the plain text field.
Press the SECURE button and observe the encrypted text.
Press the UNSECURE button and look at the decrypted text.
Check the 'new lines used' if you used new lines in the plain text
