     5    cipher.

     8  # `bcrypt` Function
     9  
    10  `bcrypt` computes a hash of the given string using the Blowfish cipher,
    11  returning a string in
    12  [the _Modular Crypt Format_](https://passlib.readthedocs.io/en/stable/modular_crypt_format.html)
    13  usually expected in the shadow password file on many Unix systems.
    14  
    15  ```hcl
    16  bcrypt(string, cost)
    17  ```
    18  
    19  The `cost` argument is optional and will default to 10 if unspecified.
    20  
    21  Since a bcrypt hash value includes a randomly selected salt, each call to this
    22  function will return a different value, even if the given string and cost are
    23  the same. Using this function directly with resource arguments will therefore
    24  cause spurious diffs. We recommend using this function only in `provisioner`
    25  blocks, or in data resources whose results are only used in `provisioner`
    26  blocks.
    27  
    28  The version prefix on the generated string (e.g. `$2a$`) may change in future
    29  versions of Terraform.

    31  ## Examples
    32  
    33  ```
    34  > bcrypt("hello world")
    35  $2a$10$D5grTTzcsqyvAeIAnY/mYOIqliCoG7eAMX0/oFcuD.iErkksEbcAa
    36  ```
