Generate a Stable Hash ID — hash

Creates a deterministic hash from one or more character inputs. Uses MD5 via base R's digest-like approach for a lightweight, dependency-free implementation.

Usage

hash_id(..., prefix = NULL)

Arguments

...: Character values to hash together. Concatenated with "|".
prefix: Optional prefix prepended to the hash (e.g., "RUN", "IND").

Value

A character string of the form prefix-hexhash or just hexhash.

Examples

hash_id("ADSL", "rule_001")
#> [1] "a0570f2e91174ffbf899427461748fbd"
hash_id("my_study", "2024-01-01", prefix = "RUN")
#> [1] "RUN-b1f41f1eb58f223c4ede5384464281e5"
