Cryptography protects information and communications through techniques such as encryption, hashing, and authentication. In Go applications, it belongs among the standard library’s ready-made building blocks for networked software, reducing the need to search for external libraries. section 1.2.2
The treatment establishes cryptography as part of Go’s practical application-development toolkit but does not descend into algorithms, API usage, or implementation trade-offs. Standard-library documentation is available through pkg.go.dev/std. section 1.2.2
