How to Convert (104/128bit) hashed key values from passphrase using java

Question

In my cisco router setting, am trying to connect my device using wep security type.
In wep security types, hexadecimal password are supported.

Reference:
https://developers.google.com/android/management/configure-networks#multiple_wifi_networks:~:text=For%20WEP%2DPSK%20passphrases%2C%20only%2040%2Dbit%20(10%2Ddigit)%20or%20104%2Dbit%20(26%2Ddigit)%20passphrases%20are%20supported.

While converting passphrase to hexadecimal,i got below (104/128bit) hashed key: "FDACCFD4471EEC4F3D03CCB88F" for passphrase (Chennai@12345)

My Question is how hashed key value is calculated? Is there any algorithm exist to achieve the above (104/128bit) hashed key conversion from passphrase in java?
