bcrypt Function
Note: This page is about Terraform 0.12 and later. For Terraform 0.11 and earlier, see 0.11 Configuration Language: Interpolation Syntax.
bcrypt computes a hash of the given string using the Blowfish cipher,
returning a string in
the Modular Crypt Format
usually expected in the shadow password file on many Unix systems.
bcrypt(string, cost)
The cost argument is optional and will default to 10 if unspecified.
Since a bcrypt hash value includes a randomly selected salt, each call to this
function will return a different value, even if the given string and cost are
the same. Using this function directly with resource arguments will therefore
cause spurious diffs. We recommend using this function only in provisioner
blocks, or in data resources whose results are only used in provisioner
blocks.
The version prefix on the generated string (e.g. $2a$) may change in future
versions of Terraform.
