As hardware gets faster, the iteration count should increase. Currently, 600,000 iterations for SHA-256 is often recommended by OWASP, though you should balance this with your server's performance.
While PBKDF2 is widely used and NIST-approved, consider Argon2 (available via golang.org/x/crypto/argon2 ) for new projects, as it is more resistant to GPU-based attacks.
A random string that ensures two users with the same password have different hashes.
The primary goal of PBKDF2 is to make . It achieves this through three main components: Password: The plain-text input from the user.
How to Download and Implement golang.org/x/crypto/pbkdf2 If you are building a secure application in Go, you likely need a way to transform user passwords into cryptographic keys. The (Password-Based Key Derivation Function 2) implementation in the Go sub-repository is the standard choice for this task.
package main import ( "crypto/sha256" "fmt" "golang.org/x/crypto/pbkdf2" ) func main() { password := []byte("my-secure-password") salt := []byte("unique-random-salt") // Parameters: password, salt, iterations, keyLength, hashFunction key := pbkdf2.Key(password, salt, 4096, 32, sha256.New) fmt.Printf("Derived Key: %x\n", key) } Use code with caution. Best Practices
To "download" or install the package into your Go module, run the following command in your terminal from your project's root directory: go get golang.org/x/crypto/pbkdf2 Use code with caution.
Once executed, Go will update your go.mod file and download the necessary source code into your local cache. You can then import it into your .go files like this: import "golang.org/x/crypto/pbkdf2" Use code with caution. Why Use PBKDF2?
