rands

Go package providing a suite of functions that use `crypto/rand` to generate cryptographically secure random strings in various formats, as well as ints and bytes.

s, _ := rands.Base64(16)       // => CYxqEdUB1Rzno3SyZu2g/g==
s, _ := rands.Base64URL(16)    // => zlqw9aFqcFggbk2asn3_aQ
s, _ := rands.Hex(16)          // => 956e2ec9e7f19ddd58bb935826926531
s, _ := rands.Alphanumeric(16) // => Fvk1PkrmG5crgOjT
s, _ := rands.Alphabetic(16)   // => XEJIzcZufHkuUmRM
s, _ := rands.Upper(16)        // => UMAGAFPPNDRGLUPZ
s, _ := rands.UpperNumeric(16) // => DF0CQS0TK9CPUO3E
s, _ := rands.Lower(16)        // => ocsmggykzrxzfwgt
s, _ := rands.LowerNumeric(16) // => rwlv7a1p7klqffs5
s, _ := rands.Numeric(16)      // => 9403373143598295

s, _ := rands.String(16, "abcdefABCDEF")                                // => adCDCaDEdeffeDeb
s, _ := rands.UnicodeString(16, []rune("九七二人入八力十下三千上口土夕大")) // => 下下口九力下土夕下土八上二夕大三

s, _ := rands.DNSLabel(16) // => z0ij9o8qkbs0ru-h

n, _ := rands.Int(2147483647)                   // => 1334400235
n, _ := rands.Int64(int64(9223372036854775807)) // => 8256935979116161233

b, _ := rands.Bytes(8) // => [0 220 137 243 135 204 34 63]
