HMAC algorithm stands for Hashed or Hash based message authentication code .It is a result of work done on developing a MAC derived from cryptographic hash functions. HMAC is a great resistant towards cryptanalysis attacks as it uses the Hashing concept twice. HMAC consists of twin benefits of Hashing and MAC, and thus is more secure than any other authentication codes. RFC 2104 has issued HMAC, and HMAC has been made compulsory to implement in IP security. The FIPS 198 NIST standard has also issued HMAC.
As the Hash Function, HMAC is also aimed to be one way, i.e, easy to generate output from input but complex the other way round.
It aims at being less effected by collisions than the hash functions.
HMAC reuses the algorithms like MD5 and SHA-1 and checks to replace the embedded hash functions with more secure hash functions, in case found.
HMAC tries to handle the Keys in more simple manner.
HMAC algorithm –
The working of HMAC starts with taking a message M containing blocks of length b bits. An input signature is padded to the left of the message and the whole is given as input to a hash function which gives us a temporary message digest MD’. MD’ again is appended to an output signature and the whole is applied a hash function again, the result is our final message digest MD.

Yesterday wasn’t a bad day but the morning started out a little busy. Ended up working through my lunch hour so I went at like 1 and chilled at a coffee shop.
When I came back had to rush through some documentation I guess my boss was waiting for, but all seems good now. For the last couple hours its been quiet, so hopefully that means my app is working fine and not that it broke so bad they don’t have time to message me lol
Gonna grab some grub now, hows your guys day going so far?

Travel allows you the thrill and excitement of adventure. When traveling is done without much of planning, it becomes an adventure as there is uncertainty and the excitement of delving with the unknown.
Storybook pumpkins. By far my favorite pumpkins every year.
We have yet to carve our pumpkins this year, but when we do, you best believe we’ll be spraying a bit of Thieves in them to make them last.
Do you carve your pumpkins or leave them whole?
Nina - The Hacker .
Brains & beauty collide with Nina. A brilliant computer scientist, who lost her job for snooping into things she shouldn’t have. She later became a street doctor known as “mother of synths” who treats synths suffering from a disease called the ruin, caused from their cybernetic augmentations. Able to hack and interface with any piece of tech, she will become one of Night City’s brightest stars. coming from myself, @ninasounduk and many others, we are working together to create a synthwave mega collab in the form of a comic series titled “Night City: Berlin”. Stay posted for more info, and go give Nina a follow if you haven’t already.
It's seen better days. Going to clean off a spot on the bench tonight and see if I can't change the frame out and replace the motors with 0802 BETAFPVs. Got a little warm during my Twich steam. Ohackit.live
Today's #GlitterfiedTuesdayTip came from when I was making one of my #HelloFresh meals for lunch! Do you ever get the meals that come with the TINY little jam jars?? And then struggle to get all the jam out?? Enter my secret weapon...the Mini Skinny Scraper! It's great for getting into TINY nooks and crannies!

💎Who is Imam Hussein?
💓who is this hussain whom the whole world is crazy about?!
⚔️What has happened so massive on Ashura in Karbala?
📣O people of the world know that I am the imam al-Qَaem 📣O people of the world know that I am the sword that takes revenge 📣O people of the world know that my grandfather Hussain was martyred while he was thirsty 📣O people of the world indeed I am the son of Hussain whose Holy body was left on the soil while it was uncovered 📣O people of the world indeed my grandfather Hussain was trampled out of spite
Imam Hussain was Prophet Muhammad 's grandson. After 50 years of Prophet Muhammad's demise, (in time of Imam Hussain), Yazid was the ruler. A cruel corrupted man who knew nothing about Islam and intended to establish a monarchy under the name of Islam. he asked for Imam Hussain's oath of allegiance in order to obtain reputation in society. Imam Hussain refused to do so in order to save the society from a cruel monarch. Therefore Yazid equipped his army to kill Hussain and his family . Yazid's army besieged Hussain and his family members in Karbala desert in Iraq .The army didn't let them drink water for 3 days. But Hussain, his beloved brother Abbas and his companions didn't surrender and kept fighting while they were thirsty. They were all martyred but their resistance disclosed the real face of Yazid and defeated him finally. We still mourn and commemorate them after 1400 years. because Imam Hussain and his 72 companions were brave men who fought evil for justice .Brave men belong to all times and all ages. May God bless them
