Bell Labs
From 1960 until 1986, Morris was a researcher at Bell Labs and worked on Multics and later Unix. Morris's contributions to early versions of Unix include the math library, the bc programming language, the program crypt, and the password encryption scheme used for user authentication. The encryption scheme was based on using a trapdoor function (now called a key derivation function) to compute hashes of user passwords which were stored in the file /etc/passwd; analogous techniques, relying on different functions, are still in use today.

Famous quotes containing the word bell:
“To be faced with what so-and-so’s mother lets him do, or what the teacher said in class today or what all the kids are wearing is to be required to reexamine some part of our belief structure. Each time we rethink our values we reaffirm them or begin to change them. Seen in this way, parenthood affords us an exceptional opportunity for growth.”
—Ruth Davidson Bell (20th century)
