caddy-hash-password - Hashes a password and writes base64caddy hash-password [--plaintext ] [--algorithm ] [--bcrypt-cost ] [--argon2id-time ] [--argon2id-memory ] [--argon2id-threads ] [--argon2id-keylen ] [flags]
Convenient way to hash a plaintext password. The resulting hash is written to stdout as a base64 string.
--plaintext The password to hash. If omitted, it will be read from stdin. If Caddy is attached to a controlling TTY, the input will not be echoed.
--algorithm Selects the hashing algorithm. Valid options are: * 'argon2id' (recommended for modern security) * 'bcrypt' (legacy, slower, configurable cost)
bcrypt-specific parameters:
--bcrypt-cost Sets the bcrypt hashing difficulty. Higher values increase security by making the hash computation slower and more CPU-intensive. Must be within the valid range [bcrypt.MinCost, bcrypt.MaxCost]. If omitted or invalid, the default cost is used.
Argon2id-specific parameters:
--argon2id-time Number of iterations to perform. Increasing this makes hashing slower and more resistant to brute-force attacks.
--argon2id-memory Amount of memory to use during hashing. Larger values increase resistance to GPU/ASIC attacks.
--argon2id-threads Number of CPU threads to use. Increase for faster hashing on multi-core systems.
--argon2id-keylen Length of the resulting hash in bytes. Longer keys increase security but slightly increase storage size.
-a, --algorithm="bcrypt" Name of the hash algorithm
--argon2id-keylen=32 Length of the resulting Argon2id hash in bytes. Longer hashes increase security but slightly increase storage size.
--argon2id-memory=47104 Memory to use in KiB for Argon2id hashing. Larger values increase resistance to GPU/ASIC attacks.
--argon2id-threads=1 Number of CPU threads to use for Argon2id hashing. Increase for faster hashing on multi-core systems.
--argon2id-time=1 Number of iterations for Argon2id hashing. Increasing this makes the hash slower and more resistant to brute-force attacks.
--bcrypt-cost=14 Bcrypt hashing cost (only used with 'bcrypt' algorithm)
-h, --help[=false] help for hash-password
-p, --plaintext="" The plaintext password
