MY
EDUCATION BACKGROUND
I hold a Bachelor of Science in Engineering (B.Sc. Engg.) in Computer Science and Engineering (CSE) from Hajee Mohammad Danesh Science and Technology University (HSTU), where I conducted my undergraduate thesis on "A Hybrid Cryptographic Scheme Using a Randomized Approach to Enhance Data Security."
Prior to that, I excelled academically, earning a perfect GPA of 5.00 in both Higher Secondary (HSC) from BAF Shaheen College, Dhaka, and Secondary School (SSC) from Kishoreganj Govt. Boys' High School, Kishoreganj.
With a strong foundation in computer science, cryptography, and data security, I aspire to further my education in blockchain and cybersecurity. While currently working as a professional full-stack developer to support myself, I remain passionate about expanding my expertise in these cutting-edge fields.

BSK Stream Cipher
November, 2020
BSK Stream Cipher
Language Used: C++
Development Tools: Dev-C++
Time Periods: November, 2020
Description: Bornomala Symmetric Key (BSK) stream cipher is a developed cipher that generated a pair of sub-keys from an input key through a complex key generation technique used in encryption. The slightest change in the input symmetric key produces an entirely different key pair. Hence, different encrypted results exhibit the reliability of the cipher along with modern cryptography.
