Quick summary
Cryptography training at Best Cybersecurity Training in Hyderabad is a intermediate classroom course in Ameerpet, Hyderabad, in our Foundation track. It covers 8 modules — cryptographic goals, symmetric cryptography, hashing and macs, asymmetric cryptography and more — with hands-on labs using tools such as OpenSSL, Python cryptography library, CyberChef. It suits developers implementing encryption, tokens or signatures.
What is the Cryptography course?
Cryptography rarely fails because an algorithm was broken. It fails because of reused nonces, weak key storage, absent certificate validation or home-made constructions. This course concentrates on those failures.
You cover symmetric and asymmetric encryption, hashing, digital signatures, TLS and PKI at a working level: enough theory to make correct decisions, with the emphasis on implementation and assessment.
Labs include breaking deliberately weak implementations, because understanding how a mistake is exploited is what makes the correct practice memorable.
Who should learn this?
- Developers implementing encryption, tokens or signatures

Practical training
Labs alternate between implementing cryptography correctly and attacking implementations that got it wrong, so each principle is learned from both directions.
Tools and technologies
- OpenSSL
- Python cryptography library
- CyberChef
- testssl.sh
- jwt_tool
- Hashcat
Labs and projects
- Decrypt data protected by a flawed mode and explain the failure
- Implement correct password storage and verify the work factor
- Assess and harden a TLS configuration end to end
- Exploit a JWT algorithm confusion flaw, then fix the implementation
Learning outcomes
- Make sound cryptographic choices for real requirements
- Spot implementation flaws during review
- Configure TLS and PKI correctly
- Explain cryptographic risk to engineering teams clearly
Career relevance
Roles where these skills are directly used:
- Application security engineer
- Security architect
- Penetration tester
- Secure software developer
Cryptography training — FAQs
Is this course heavy on mathematics?
No. Enough theory is covered to make correct decisions; the focus is applied use, configuration and reviewing implementations.
Will I implement algorithms from scratch?
Only as small teaching exercises. The strongest lesson in the course is to use vetted libraries rather than writing your own.
Does it cover post-quantum cryptography?
At awareness level — what is changing, the migration timeline and what it means for key and certificate planning.
Is it useful for developers?
Highly. Most findings in this area come from application code: token handling, password storage and misused libraries.
