Go provides built-in support for cryptography and encryption through its standard library, which includes packages for hash functions, symmetric encryption, and asymmetric encryption.
**crypto** package in Go provides a set of common cryptographic primitives such as hash functions, message authentication codes, and symmetric and asymmetric encryption algorithms. The package supports various encryption modes, including AES, RSA, and elliptic curve cryptography.
Go also has built-in support for TLS encryption through the
**crypto/tls** package. This package provides a simple interface for establishing encrypted connections between clients and servers over TCP or UDP.
To ensure security in Go, it is essential to follow secure coding practices such as input validation, proper error handling, and avoiding race conditions in concurrent code. It is also important to stay up to date with the latest security updates and patches to the Go runtime and standard library. Additionally, third-party security libraries and tools can be used to augment Go's built-in security capabilities.
