Cryptography courses can help you learn encryption techniques, hashing algorithms, digital signatures, and secure communication protocols. You can build skills in threat modeling, cryptanalysis, and implementing security measures to protect sensitive data. Many courses introduce tools like OpenSSL, GnuPG, and various programming libraries that facilitate secure coding practices and help you apply cryptographic principles in real-world applications.
