go-password-validator
A lightweight Go library for password strength validation using entropy calculations, without arbitrary character rules.
What is go-password-validator?
go-password-validator is a Go library that validates password strength using entropy calculations instead of arbitrary rules like requiring uppercase letters or special characters. It helps developers ensure passwords are cryptographically strong by measuring entropy in bits, providing a lightweight and fast solution for server-side validation. The library avoids external dependencies and large datasets, focusing on raw cryptographic strength for reliable security assessments.
Go developers building applications that require secure password validation, such as authentication systems, user registration flows, or password strength meters. It's particularly useful for those who prefer entropy-based security over traditional rule-based approaches.
Developers choose go-password-validator for its simplicity, speed, and focus on entropy-based validation without arbitrary rules. Its lightweight design, lack of external dependencies, and client-safe error messages make it a reliable choice for secure and efficient password strength assessment in Go applications.
