  - name: "my_password2"
    prompt: "Enter password2"
    private: yes
    encrypt: "md5_crypt"
    confirm: yes

`sun_md5_crypt` - Sun MD5 Crypt
`sha256_crypt` - SHA-256 Crypt
`sha512_crypt` - SHA-512 Crypt
`apr_md5_crypt` - Apache’s MD5-Crypt variant
`phpass` - PHPass’ Portable Hash
`pbkdf2_digest` - Generic PBKDF2 Hashes
`cta_pbkdf2_sha1` - Cryptacular’s PBKDF2 hash
`dlitz_pbkdf2_sha1` - Dwayne Litzenberger’s PBKDF2 hash
