Description

Cryptography is an educational security app for students, developers, cybersecurity beginners and exam learners who want to understand cryptography, ciphers, hashing, RSA, keys and secure communication without scattered notes.

If terms like AES, public key, hash digest, modular arithmetic or digital signature feel difficult, this app gives you a structured path. Learn core concepts, revise offline, use practical crypto tools and build confidence for classes, projects, interviews and security fundamentals.

🔐 Core Features Deep Dive

✅ Structured cryptography lessons
Study foundations, history, terminology, classical ciphers, steganography, symmetric cryptography, block ciphers, stream ciphers, cipher modes, public-key cryptography, PKI, hashing, MACs, digital signatures and key management.

✅ Math made easier
Learn the number theory behind cryptography through modular arithmetic, greatest common divisor, extended Euclidean algorithm, modular inverse, prime numbers, factorization, groups, fields, CRT, randomness, entropy and pseudorandom generation.

✅ Classical and modern cipher practice
Use 21 free tools for ASCII to binary, binary to ASCII, text to hex, hex to text, decimal-binary-hex conversion, XOR, bitwise operations, modular exponentiation, Caesar cipher, ROT13, Vigenere, Affine cipher, Base64, hash digest and password entropy.

✅ Security models and attacks
Understand threat types, OSI and network security ideas, storage pitfalls, key handling, perfect secrecy, statistical testing, one-way functions and the importance of secure design choices.

✅ 30 How-To lessons
Read practical How-To content that explains ciphers, keys, hashes, encoding, randomness, passwords and security concepts in a clear learning format.

✅ Offline, bookmark and search
Read lessons offline after installation, bookmark difficult topics and search cryptography, RSA, AES, cipher, hash, HMAC, PKI, entropy, prime numbers and key management quickly.

👥 Who Is This For?

• Students can revise cryptography theory before exams, viva sessions or lab work. The app helps connect textbook definitions with examples and tools.

• Developers can understand the ideas behind encryption, hashing, Base64, password entropy and digital signatures before using real security libraries.

• Cybersecurity beginners can build a foundation in classical ciphers, public-key cryptography, message integrity, secure keys and common attack concepts.

• Interview learners can quickly review RSA, DES, AES, Diffie-Hellman, ECC, hashing, MACs, signatures, entropy and modular arithmetic from one offline app.

💡 Why Choose Cryptography?

Many resources explain theory without practice, while separate tools often do not teach the meaning behind results. Cryptography combines organized lessons, How-To guidance, bookmarks, search and free crypto calculators in one focused mobile learning experience.

❓ Frequently Asked Questions

Comments on Cryptography for Android

★★★★★ ganesh gurung · Dec 19, 2017

Very well detailed about the topics... best app to learn cryptography in the play store IMO.

★★★★★ Samuel Gyasiborr · Apr 5, 2022

This is so exciting yet to try the pro. I've been looking for a soft copy book for a good amount of time and now this is satisfying. Can't describe my joy

★☆☆☆☆ ARSHAD BASHA · Mar 3, 2018

Idiot ! 😡 All the data is copied from tutorials point website.
