从php libsodium sodium_crypto_pwhash_str()返回的长度

How long is the string returned by sodium_crypto_pwhash_str() in PHP? Does it vary with the plaintext? The options $opslimit and $memlimit? Basically, I want to know how long a database field to give it.

    The maximum length of a hashed password is crypto_pwhash_STRBYTES, which is 128 bytes.

    This constant is not exposed in the PHP bindings yet, but I'm going to add it soon.

    Update: this has been added to the PECL extension.
