For who cares about it, its called "freeBSD md5 crypt" or "unix md5 crypt".
some text i had lying around
MD5 crypt was written by Poul-Henning Kamp for FreeBSD. The main reason
for using MD5 was to avoid problems with American export prohibitions on
cryptographic products, and to allow for a longer password length than the
8 characters used by DES crypt. The password length is restricted only by
MD5's maximum message size of 264 bits. The salt can vary from 12 to 48
bits.
MD5 crypt hashes the password and salt in a number of different
combinations to slow down the evaluation speed. Some steps in the
algorithm make it doubtful that the scheme was designed from a
cryptographic point of view--for instance, the binary representation of
the password length at some point determines which data is hashed, for
every zero bit the first byte of the password and for every set bit the
first byte of a previous hash computation.
The output is the concatenation of the version identifier ``$1$'', the
salt, a ``$'' separator, and the 128-bit hash output.
MD5 crypt places virtually no limit on the size of passwords, while bcrypt
has a maximum of 55 bytes. We do not consider this a serious limitation of
bcrypt, however. Not only are users unlikely to choose such long
passwords, but if they did, MD5 crypt's 128-bit output size would become
the limiting factor in security. A brute force attacker could more easily
find short strings hashing to the same value as a user's password than
guess the actual password. Finally, like DES crypt, MD5 crypt has fixed
cost.

The server i need these hashed passwords for is freeradius, however on
that site is no real information about this.
As you can see the $1$ seems to tell the server it is encrypted, as i
understood.
