Random — Inrun

Generate cryptographically secure random values: hex, base64 and alphanumeric strings, and UUIDs. They return a different value on every call, so evaluate them once, when a secret is first created, and keep the result; evaluated on every reconcile, a password changes every time.

Reference

Function	Description
`randomAlphanumeric`	Generates a cryptographically random alphanumeric string of exactly `n` characters.
`randomBase64`	Generates `n` random bytes and returns them as a URL-safe base64 string.
`randomHex`	Generates `n` random bytes and returns them as a hex-encoded string.
`uuidv4`	Generates a random UUID v4 string in standard `8-4-4-4-12` hex format.

Functions

randomAlphanumeric

randomAlphanumeric generates a cryptographically random alphanumeric string of exactly n characters. Characters are drawn from [a-zA-Z0-9].

{{ randomAlphanumeric 12 }}  → "k7Xm3pQs9vR2"

randomBase64

randomBase64 generates n random bytes and returns them as a URL-safe base64 string. The output length is approximately ceil(n * 4/3) characters.

{{ randomBase64 16 }}  → "47H1Wtj_DBL6gy0hBE-49w=="

randomHex

randomHex generates n random bytes and returns them as a hex-encoded string. The output is 2n characters long.

{{ randomHex 8 }}  → "a3f8b2c1d4e5f6a7"

uuidv4

uuidv4 generates a random UUID v4 string in standard 8-4-4-4-12 hex format. Same entropy as randomHex 16, formatted as a UUID for systems that expect that shape.

{{ uuidv4 }}  → "f47ac10b-58cc-4372-a567-0e02b2c3d479"
