Seedgen

Generate reproducible seeds and deterministic test data. Use when creating random seeds, rotating salt values, auditing randomness, storing seed records.

Random seed and data generator. Generate random strings, hex, bytes, integers, floats, UUIDs, passwords, and batch outputs — using /dev/urandom and standard tools.

Commands

Command	Description
seedgen string <length>	Random alphanumeric string of given length
seedgen hex <bytes>	Random hex string (2 hex chars per byte)
seedgen bytes <count>	Random bytes, base64 encoded
seedgen int <min> <max>	Random integer in range [min, max]
seedgen float	Random float between 0 and 1
seedgen pick <item1> <item2> ...	Randomly pick one item from a list
seedgen uuid	Generate a UUID v4
seedgen password <length>	Generate a strong mixed-char password
seedgen batch <type> <count> [args]	Generate multiple values at once
seedgen version	Show version

Examples

seedgen string 32          # → "aB3kQ9..."
seedgen hex 16             # → "4f2a1c..."
seedgen bytes 64           # → base64-encoded random bytes
seedgen int 1 100          # → 42
seedgen float              # → 0.73812...
seedgen pick red green blue # → "green"
seedgen uuid               # → "550e8400-e29b-41d4-..."
seedgen password 20        # → "kP#9xL!mQ..."
seedgen batch string 5 16  # → 5 random 16-char strings
