Developer Glossary
Plain-English definitions of encoding standards, cryptographic primitives, API protocols, and data formats used across quickhelp.dev tools. Each entry links to a full explanation with examples, use cases, and related tools.
- Base64Binary-to-text encoding scheme that represents binary data as printable ASCII characters.
- BinaryBase-2 number system using only digits 0 and 1 — the native language of computers.
- CSVComma-Separated Values — simple tabular text format widely used for data exchange.
- Hash functionOne-way function that maps data of any size to a fixed-length digest.
- HexadecimalBase-16 number system using digits 0–9 and letters A–F, common in computing.
- HMACHash-based Message Authentication Code — keyed cryptographic MAC using a hash function.
- JSONJavaScript Object Notation — lightweight, human-readable data interchange format.
- JSON SchemaVocabulary for annotating and validating JSON document structure.
- JWTJSON Web Token — compact, URL-safe claims representation used in auth flows.
- llms.txtEmerging standard for structured AI-readable site summaries, analogous to robots.txt.
- MCPModel Context Protocol — open standard for AI tool discovery and invocation.
- OAuth 2.0Authorization framework for delegating access without sharing credentials.
- OpenAPIMachine-readable HTTP API specification format (formerly Swagger).
- RegexRegular expressions — patterns for matching and extracting text.
- REST APIArchitectural style for HTTP APIs using resources, verbs, and stateless requests.
- SHA-256Secure Hash Algorithm producing a 256-bit digest; backbone of TLS, Git, and Bitcoin.
- Unix timestampCount of seconds elapsed since 1970-01-01T00:00:00Z, the universal epoch.
- URL encodingPercent-encoding scheme that safely embeds arbitrary bytes in URLs.
- UUIDUniversally Unique Identifier — 128-bit label guaranteed to be globally unique.
- ZodTypeScript-first schema declaration and runtime validation library.
