Lets-Chat : Weekly update #5

Lets-chat

Here is my weekly update for GSoC project under +Tong Hui and +Mario Behling 





Issue #8 : Key generation for group OTR chat [1] 

• Implemented the fingerprint of key using SHA-1 

• Implemented the fingerprint of key using SHA-256

• Implemented the fingerprints thus generated as 4 digit hex format

• I will be pushing the fingerprints as 8-digit hex format in my next commit

• Figured out that use of regex, instead of the loop I am using would be better as seen in TODO in my this week's commit 

• Initially I was using nested loops to implement 4 digit hex format which I reduced to a loop for reducing complexity

• Output is attached at [1]  as well as below for quick reference

Issue #19 Cannot create and enter in room [2]

• +Tong Hui raised this bug , it was because of my commits that I pushed for Issue #17 generated by me

• Fixed this bug

• Closed Issue #19

Issue #17  [3]

• I raised this issue as I felt it would be better for users to have password protected rooms by default

• I pushed changed for this issue, but somehow it is giving a bug raised in Issue #19 at the moment

Issue #16 [4]

• I raised this issue earlier, I tested it, worked fine

•  +Tong Hui tested it as well and we have closed this one :)

I plan to work on Issue #15 [5] , I have already pushed some work :) and as suggested by my mentor +Tong Hui

Lets-chat : Weekly update #4

Lets - chat 

Here is my weekly update for GSoC project under +Tong Hui and +Mario Behling 

Issue #8 

• Added execution time 
• Made the key length as 1536 bits as required for OTR encryption
• Planing to implement fingerprint of the key as suggested by my mentor +Tong Hui 

You can go through this issue at [1], and could see the snapshots of the terminal output after each commit for reference.

Issue  #15 

• Raised this issue to implement encryption and decryption for OTR
• Implemented Hash algorithm using crypto. SHA 512 using the private hex key generated by Diffie Hellman last week by me
• Implemented AES encryption decryption on a sample text using Hmac . 

I am planing to work on improving issue #15 this week. [2] 

Issue #16

• Raised this issue to have some more quotes for raptorize plugin 
• Using this, when any of those quotes are messaged, a dinosaur appears which is quite interactive for end users
• Added some frequently used words to raptorize

Lets-chat : Weekly update GSoC #3

Lets-chat 

Here is the weekly update for my GSoC project, lets-chat under +Tong Hui and +Mario Behling 

• Key - Generation : Issue #8 [1] 

As you could see, I initially used tried using random number generator [2] 

Then, I planned to use hardcore value : Number.MAX_VALUE and Number.MIN_VALUE instead of digits .  [3]

Later, I implemented key generation using crypto-js libraries [4] through Diffie Hellman as shown below :

Crypto-js libraries can be accessed at [5]

And later increased the key length as could be seen :

And added execution time [6]

Apart from Issue #8, I contributed to other issues as well :

Issue #10 [7] 

• Issue #10 involved adding quick icons for reference, I provided one for key generation [8]

Issue #9 [9]

• Issue #9 involves adding a menu for group encryption. There was a syntax error which I fixed. [10]

Issue #12 [11]

• I raised this issue to have localised date in transcript. [12]

Issue #11 [13]

• I raised this issue in order to have some hot keys in lets-chat. It is in progress, not yet resolved.
