Massive data sets, which are housed on mainframes, could move onto a distributed architecture. This, in part, gave rise to the “client-server” architecture, which supported the development of relational database systems. With the advent of personal computers and private networks, similar computational capabilities were now housed both on the clients, as well as the servers. Access to mainframes is mainly by “dumb terminals”, which only take inputs and outputs, and do not store or process data. They typically house all computing power, memory, data storage, and code. Mainframe computers are largely centralized. Looking back to the last half century of computer technologies and architectures, one may observe a trend of fluctuation between the centralization and subsequent decentralization of computing power, storage, infrastructure, protocols, and code.

These are the other Javascript files included in this repository: The following are public methods on the Base32 module:ĭecode str from Base32 into its original string. If data is malformed, an exception is thrown.Įncode/decode a string using the RFC 4648 Base32 format.

decode(str) : Ĭonverts Bencoded str back into its original type.

Arrays and objects can also only contain the aforementioned types. Obj can only be a string, number, array, or object. The following are public methods on the Bencode module: The return value is a Uint8Array of length 20.Įncode/decode an object or string using the Bencode format. Ĭomputes and returns the SHA1 digest of all the data input so far. Value_array can be a string, with each character in the range or a ( typed) array, with each value in the range.

Update the internal state of the hashing object with the values contained in value_array. Resets the internal state of the instance. The following are public methods on the SHA1 class: Data can be input in chunks, and the digest can be calculated at any point without modifying the internal state. They are primarly designed for web usage, but they can be trivially modified to be used with something such as node.js.Ĭomputes the SHA-1 hash of the specified data using the basic algorithm described in RFC 3174, with a paradigm similar to python's hashlib. base32.js - Base32 encoding/decoding library.bencode.js - Bencode encoding/decoding library.The following Javascript libraries are used on this page:
