In , is the conversion of into . cryptography decryption ciphertext cleartext Decryption is a cryptographic primitive: it transforms a ciphertext message into plaintext using a cryptographic algorithm called a . Like encryption, decryption in modern ciphers is performed using a specific algorithm and a secret, called the . Since the algorithm is often public, the key must stay secret if the encryption stays secure. cipher key Decryption is the reverse of and if the key stays secret, decryption without knowing the specific secret, decryption is mathematically hard to perform. How hard depends on the security of the cryptographic algorithm chosen and evolves with the progress of . encryption cryptanalysis Learn more Technical reference Encryption and Decryption View Previous Terms: Block cipher mode of operation Certificate authority Challenge-response authentication Cipher Cipher suite Ciphertext CORS CORS-safelisted request header CORS-safelisted response header Cross-site scripting Cryptanalysis Cryptographic hash function Cryptography CSP CSRF Digital certificate DTLS (Datagram Transport Layer Security) Encryption Forbidden header name Forbidden response header name Hash HMAC HPKP HSTS HTTPS Key MitM OWASP Preflight request Public-key cryptography Reporting directive Robots.txt Same-origin policy Session Hijacking SQL Injection Symmetric-key cryptography TOFU Transport Layer Security (TLS) Credits Source: https://developer.mozilla.org/en-US/docs/Glossary/Decryption Published under license Open CC Attribution ShareAlike 3.0
