| 2. There are several key finding methods such as | ||
| - [Kasiski examination](https://en.wikipedia.org/wiki/Kasiski_examination) | ||
| - [Index of coincidence](https://en.wikipedia.org/wiki/Index_of_coincidence) | ||
| 3. Once key is found, we can use [frequency analysis](https://en.wikipedia.org/wiki/Frequency_analysis) to crack the cipher. |
There was a problem hiding this comment.
Once the key length is found.

Description
Provided the explanation for vignere cipher in the cipher directory of the English language. Added brief encryption and decryption algorithm along with an example. Then described the complexity analysis of the scheme. Furthermore, added resources about regarding the cryptanalysis(attack) of the cipher and caution regarding not using it for real life purposes.
Also attached the implementation links in python, C++ and javascript.
