DEA is the commonly used acronym for the Drug Enforcement Administration, a United States federal law enforcement agency.
DEA may also refer to:
Pretty Good Privacy (PGP) is an encryption program that provides cryptographic privacy and authentication for data communication. PGP is used for signing, encrypting, and decrypting texts, e-mails, files, directories, and whole disk partitions and to increase the security of e-mail communications. Phil Zimmermann developed PGP in 1991.
The Regulation of Investigatory Powers Act 2000 (c.23) is an Act of the Parliament of the United Kingdom, regulating the powers of public bodies to carry out surveillance and investigation, and covering the interception of communications. It was introduced by the Tony Blair Labour government ostensibly to take account of technological change such as the growth of the Internet and strong encryption.
Computer and network surveillance is the monitoring of computer activity and data stored locally on a computer, or data being transferred over computer networks such as the Internet. This monitoring is often carried out covertly and may be completed by governments, corporations, criminal organizations, or individuals. It may or may not be legal and may or may not require authorization from a court or other independent government agencies. Computer and network surveillance programs are widespread today and almost all Internet traffic can be monitored.
The Drug Enforcement Administration is a United States federal law enforcement agency under the U.S. Department of Justice tasked with combating drug trafficking and distribution within the U.S. It is the lead agency for domestic enforcement of the Controlled Substances Act, sharing concurrent jurisdiction with the Federal Bureau of Investigation, the U.S. Immigration and Customs Enforcement, and U.S. Customs and Border Protection. The DEA has sole responsibility for coordinating and pursuing U.S. drug investigations both domestically and abroad.

DPA may refer to:
The Home Office (HO), also known as the Home Department, is a ministerial department of the Government of the United Kingdom, responsible for immigration, security, and law and order. As such, it is responsible for policing in England and Wales, fire and rescue services in England, visas and immigration, and the Security Service (MI5). It is also in charge of government policy on security-related issues such as drugs, counter-terrorism, and ID cards. It was formerly responsible for Her Majesty's Prison Service and the National Probation Service, but these have been transferred to the Ministry of Justice. The Cabinet minister responsible for the department is the home secretary, a post considered one of the Great Offices of State; it has been held since July 2019 by Priti Patel.
The Clipper chip was a chipset that was developed and promoted by the United States National Security Agency (NSA) as an encryption device that secured "voice and data messages" with a built-in backdoor that was intended to "allow Federal, State, and local law enforcement officials the ability to decode intercepted voice and data transmissions." It was intended to be adopted by telecommunications companies for voice transmission. Introduced in 1993, it was entirely defunct by 1996.
Gas chromatography–mass spectrometry (GC-MS) is an analytical method that combines the features of gas-chromatography and mass spectrometry to identify different substances within a test sample. Applications of GC-MS include drug detection, fire investigation, environmental analysis, explosives investigation, and identification of unknown samples, including that of material samples obtained from planet Mars during probe missions as early as the 1970s. GC-MS can also be used in airport security to detect substances in luggage or on human beings. Additionally, it can identify trace elements in materials that were previously thought to have disintegrated beyond identification. Like liquid chromatography–mass spectrometry, it allows analysis and detection even of tiny amounts of a substance.
Methylamine is an organic compound with a formula of CH3NH2. This colorless gas is a derivative of ammonia, but with one hydrogen atom being replaced by a methyl group. It is the simplest primary amine.
Diethanolamine, often abbreviated as DEA or DEOA, is an organic compound with the formula HN(CH2CH2OH)2. Pure diethanolamine is a white solid at room temperature, but its tendencies to absorb water and to supercool meaning that it is often encountered as a colorless, viscous liquid. Diethanolamine is polyfunctional, being a secondary amine and a diol. Like other organic amines, diethanolamine acts as a weak base. Reflecting the hydrophilic character of the secondary amine and hydroxyl groups, DEA is soluble in water. Amides prepared from DEA are often also hydrophilic. In 2013, the chemical was classified by the International Agency for Research on Cancer as "possibly carcinogenic to humans" (Group 2B).
2,2,2-Trichloroethanol is the chemical compound with formula Cl
3C−CH
2OH. Its molecule can be described as that of ethanol, with the three hydrogen atoms at position 2 replaced by chlorine atoms. It is a clear flammable liquid at room temperature, colorless when pure but often with a light yellow color.
Parallel construction is a law enforcement process of building a parallel, or separate, evidentiary basis for a criminal investigation in order to conceal how an investigation actually began.

Cryptography, or cryptology, is the practice and study of techniques for secure communication in the presence of adversarial behavior. More generally, cryptography is about constructing and analyzing protocols that prevent third parties or the public from reading private messages; various aspects in information security such as data confidentiality, data integrity, authentication, and non-repudiation are central to modern cryptography. Modern cryptography exists at the intersection of the disciplines of mathematics, computer science, electrical engineering, communication science, and physics. Applications of cryptography include electronic commerce, chip-based payment cards, digital currencies, computer passwords, and military communications.

Kolab Now is a web-based email and groupware service, based completely on free and open-source software. It is owned and operated by Kolab Systems AG and was formerly known as MyKolab.
The Narcotics and Dangerous Drugs Information System, or NADDIS, is a data index and collection system operated by the United States Drug Enforcement Administration (DEA). Comprising millions of DEA reports and records on individuals, NADDIS is a system by which intelligence analysts, investigators and others in law enforcement retrieve reports from the DEA's Investigative Filing and Reporting System (IFRS). NADDIS is thought to have become the most widely used, if least known, tool in drug law enforcement.
