Hash

Compute a cryptographic hash of a string, or verify an HMAC signature.

Route

POST /api/hash

Parameters

Field	Type	Required	Default	Description
input	string	Yes	—	String to hash
algorithm	string	No	sha256	md5, sha1, sha256, sha512, blake3, hmac-sha256
encoding	string	No	hex	Output encoding: hex, base64
key	string	No	—	HMAC key. Required when algorithm is hmac-sha256

Response

Field	Type	Description
hash	string	Computed hash value
algorithm	string	Algorithm used
encoding	string	Output encoding used

Examples

SHA-256 hash

curl -X POST https://morso.dev/api/hash \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"input": "hello world"}'

{
  "hash": "b94d27b9934d3e08a52e52d7da7dabfac484efe37a5380ee9088f7ace2efcde9",
  "algorithm": "sha256",
  "encoding": "hex"
}

HMAC-SHA256

curl -X POST https://morso.dev/api/hash \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"algorithm": "hmac-sha256", "input": "hello world", "key": "my-secret"}'

{
  "hash": "cf405b2def200d91098da8663e531d579ae1c71c90fe73d623ae2138eef2ad8b",
  "algorithm": "hmac-sha256",
  "encoding": "hex"
}

Base64 encoding

curl -X POST https://morso.dev/api/hash \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"input": "hello world", "encoding": "base64"}'

{
  "hash": "uU0nuZNNPgilLlLX2n2r+sSE7+N6U4DukIj3rOLvzek=",
  "algorithm": "sha256",
  "encoding": "base64"
}

Errors

• 422 — algorithm is hmac-sha256 but key is missing.
