Go Cryptography: Secure Your Applications with the Standard Library

Building secure software requires a solid understanding of how to protect sensitive data from unauthorized access. Go provides a powerful, highly optimized standard library specifically designed to handle modern cryptographic operations safely and efficiently. In this written course, you will learn the foundational concepts of cryptography and how to apply them directly in your Go applications. You will transition from writing basic programs to implementing industry-standard security practices, ensuring your user passwords, messages, and files remain secure. What you'll learn: * Understand the core terminology of cryptography, including plaintext, ciphertext, and keys * Generate cryptographically secure random numbers using the standard library * Implement secure password hashing and verification using modern algorithms * Encrypt and decrypt data using symmetric encryption methods like AES-GCM * Configure asymmetric encryption and digital signatures using RSA and ECDSA * Apply secure hashing and checksums to verify data integrity This text-only guide starts with essential security concepts and definitions before moving into hands-on code examples. You will read clear explanations of Go's built-in cryptographic packages and practice applying them through step-by-step written exercises. This course is designed for Go developers who are new to cryptography and want to build secure applications. A basic familiarity with Go syntax is helpful, but no prior background in security or advanced mathematics is required. Start reading today to build safer, more resilient Go applications.
