In cryptography, DEAL (Data Encryption Algorithm with Larger blocks) is a symmetric block cipher derived from the Data Encryption Standard (DES). Its design was presented by Lars Knudsen at the SAC conference in 1997, and submitted as a proposal to the AES contest in 1998 by Richard Outerbridge.
DEAL is a Feistel network which uses DES as the round function. It has a 128-bit block size and a variable key size of either 128, 192, or 256 bits; with 128-bit and 192-bit keys it applies 6 rounds, or 8 rounds with 256-bit keys. It has performance comparable to Triple DES, and was therefore relatively slow among AES candidates.

A deal, or deals may refer to:
The New Deal was a series of economic, social, and political reforms in response to the Great Depression in the United States under the first and second administrations of President Franklin D. Roosevelt. Following a demand-side economic theory, Roosevelt sought to utilize the authority of the federal government to increase spending and introduce programs to spur growth and combat issues specific to the depression, such as unemployment, labor relations, financial reform, and social welfare. Roosevelt introduced the phrase when accepting the Democratic Party presidential nomination in the 1932 United States presidential election, winning in a landslide over incumbent Herbert Hoover, whose administration was widely viewed as ineffective. Roosevelt attributed the Depression to inherent market instability and inadequate aggregate demand (based on the Keynesian economic model), and argued that stabilizing and rationalizing the economy required massive government intervention. During Roosevelt's first hundred days in office in 1933 until 1935, Roosevelt introduced what historians refer to as the "First New Deal", which focused on the "3 R's": relief for the unemployed and for the poor, recovery of the economy back to normal levels, and reforms of the financial system to prevent a repeat depression. Roosevelt signed the Emergency Banking Act, which authorized the Federal Reserve to insure deposits to restore confidence, and the 1933 Banking Act made this permanent with the Federal Deposit Insurance Corporation (FDIC). Other laws created the National Recovery Administration (NRA), which allowed industries to create "codes of fair competition"; the Securities and Exchange Commission (SEC), which protected investors from abusive stock market practices; and the Agricultural Adjustment Administration (AAA), which raised rural incomes by controlling production. Public works were undertaken in order to find jobs for the unemployed (25 percent of the workforce when Roosevelt took office): the Civilian Conservation Corps (CCC) enlisted young men for manual labor on government land, and the Tennessee Valley Authority (TVA) promoted electricity generation and other forms of economic development in the drainage basin of the Tennessee River. Although the First New Deal helped many find work and restored confidence in the financial system, by 1935 stock prices were still below pre-Depression levels and unemployment still exceeded 20 percent. From 1935 to 1938, the "Second New Deal" introduced further legislation and additional agencies which focused on job creation and on improving the conditions of the elderly, workers, and the poor. The Works Progress Administration (WPA) supervised the construction of bridges, libraries, parks, and other facilities, while also investing in the arts; the National Labor Relations Act guaranteed employees the right to organize trade unions; and the Social Security Act introduced pensions for senior citizens and benefits for the disabled, mothers with dependent children, and the unemployed. The Fair Labor Standards Act prohibited child labor, and enshrined a 40-hour work week and national minimum wage. In 1938, the Republican Party gained seats in Congress and joined with conservative Democrats to block further New Deal legislation, and some of it was declared unconstitutional by the Supreme Court. The New Deal produced a political realignment, reorienting the Democratic Party's base to the New Deal coalition of labor unions, blue-collar workers, big city machines, racial minorities (most importantly African-Americans), white Southerners, and intellectuals. The realignment crystallized into a powerful liberal coalition which dominated presidential elections into the 1960s, as an opposing conservative coalition largely controlled Congress in domestic affairs from 1939 onwards. Historians still debate the effectiveness of the New Deal programs, although most accept that full employment was not achieved until the United States' entry into World War II in 1941.
Kimberley Ann Deal (born June 10, 1961) is an American singer and rock musician who is the lead vocalist and rhythm guitarist of the Breeders, and was the original bassist and co-vocalist of the alternative rock band the Pixies. Deal joined the Pixies in January 1986, adopting the stage name Mrs. John Murphy for the albums Come on Pilgrim and Surfer Rosa. Following Doolittle and the Pixies' hiatus, she formed the Breeders with Tanya Donelly of Throwing Muses, Josephine Wiggs of the Perfect Disaster, and Britt Walford of Slint; following the band's debut album Pod, her twin sister Kelley Deal replaced Donelly and Jim Macpherson replaced Walford. The Pixies broke up in early 1993, and Deal returned her focus to the Breeders, who released the platinum-selling album Last Splash in 1993, featuring the popular single "Cannonball". In 1994, the Breeders went on hiatus after Kelley entered drug rehabilitation. During the hiatus, Deal adopted the stage name Tammy Ampersand and formed the short-lived band the Amps, recording a single album, Pacer, in 1995. After her own stint in drug rehabilitation, Deal reformed the Breeders with a new lineup for Title TK in 2002 and Mountain Battles in 2008. Deal reunited with the Pixies in 2004, and left in 2013 to concentrate on the Breeders, who toured for the 20th anniversary of Last Splash. In 2018, the Breeders released their fifth album, All Nerve, their first to reunite the Deals, Wiggs, and Macpherson since Last Splash. In 2024, Deal released her debut solo album, Nobody Loves You More.
Before the 1921 destruction of Tulsa’s Greenwood District, Black residents had created a remarkable center of business and community life. The district included stores, professional offices, entertainment venues and homes owned by Black citizens. Understanding Greenwood means learning what was built—not only what was burned.
