random

Cryptographically secure random utilities built on crypto/rand.

Features

• Secure random numbers: Int, Intn, IntRange, Float64, Bytes
• Random strings with custom charsets: String, StringWithCharset
• Sampling and shuffling: Shuffle, Sample, Choice, Permutation
• Random colors: HexColor, RGBColor, HSLColor
• UUID v4 (RFC 4122)

All functions use crypto/rand and are safe for concurrent use.

Character sets

CharsetAlphaLower, CharsetAlphaUpper, CharsetAlpha, CharsetNumeric, CharsetAlphaNum, CharsetHexLower, CharsetHexUpper, CharsetBase62, CharsetBase64URL, CharsetSymbol.

Quick start

import "github.com/LingByte/ling-base/common/random"

n := random.IntRange(1, 100)
s := random.String(16, random.CharsetAlphaNum)
b := random.Bytes(32)
id := random.UUID() // e.g. "550e8400-e29b-41d4-a716-446655440000"
