The salt and the encrypted password are both mashed into the string YtChlvAGYzva2.
From the Shadow Password Howto:
When a user picks or is assigned a password, it is encoded with a
randomly generated value called the salt. This means that any
particular password could be stored in 4096 different ways. The salt
value is then stored with the encoded password.
When a user logs in and supplies a password, the salt is first
retrieved from the stored encoded password.
The longer password strings you see with modern systems separate the hash using $. But for the older systems, it was just mashed in (Wikipedia):
Earlier versions of Unix used a password file (/etc/passwd) to store
the hashes of salted passwords (passwords prefixed with two-character
random salts). In these older versions of Unix, the salt was also
stored in the passwd file (as cleartext) together with the hash of the
In your example, I believe that the salt is "Yt" and the encrypted password is "ChlvAGYzva2". It's literally the first two characters of the string.
