Location of target nodes is specified through inventory configuration lists (INI or YAML formatted) located at /etc/ansible/hosts (on Linux). [14] [25] The configuration file lists either the IP address or hostname of each node that is accessible by Ansible. In addition, nodes can be assigned to groups. [14] An example inventory format :
The data produced in the previous step is hashed with a cryptographic hash function such as SHA-1 or SHA-2. If desired, the hash function output can be truncated to provide a shorter, more convenient fingerprint. This process produces a short fingerprint which can be used to authenticate a much larger public key.

When a user enters a password for authentication, a hash is computed for it and then compared to the stored hash for that user. Authentication fails if the two hashes do not match; moreover, authentication would equally fail if a hashed value were entered as a password, since the authentication system would hash it a second time.
The likelihood of recovering the preimage depends on the input set size and the speed or cost of computing the hash function. A common example is the use of hashes to store password validation data. Rather than store the plaintext of user passwords, an access control system typically stores a hash of the password.
The table of HA1 values must therefore be protected as securely as a file containing plaintext passwords. [12] Digest access authentication prevents the use of a strong password hash (such as bcrypt) when storing passwords (since either the password, or the digested username, realm and password must be recoverable)
Comparison of supported cryptographic hash functions. Here hash functions are defined as taking an arbitrary length message and producing a fixed size output that is virtually impossible to use for recreating the original message.
This file disappears if the floppy is moved to the B: drive, and even moving its location within the disk hierarchy requires the user-facing directories to be updated. In CAS, only the internal mapping from key to physical location changes, and this exists in only one place and can be designed for efficient updating.
