# (chibi crypto sha2)

Implementation of the SHA-2 (Secure Hash Algorithm) cryptographic hash.

#### `(sha-224 src)`

Computes SHA-224 digest of the `src` which can be a string, a bytevector, or a binary input port. Returns a hexadecimal string (in lowercase).

#### `(sha-256 src)`

Computes SHA-256 digest of the `src` which can be a string, a bytevector, or a binary input port. Returns a hexadecimal string (in lowercase).

#### `(sha-224 src)`

#### `(sha-256 src)`
