Translation guide
The practice and study of techniques for secure communication in the presence of adversaries. This guide covers how to express the concept of cryptography in Japanese, from the academic field to everyday encryption.
Referring to cryptography as a discipline, research area, or university subject.
Referring to the act or process of using codes and ciphers to protect information.
Referring to the study of breaking codes and ciphers, often contrasted with cryptography.
When discussing cryptography in a broad, non-technical sense, such as in news or casual conversation.
暗号学 is the broadest term for the science of cryptography. 暗号理論 focuses on mathematical theory, while 暗号技術 emphasizes practical implementation and engineering. Use 暗号学 for the academic discipline, 暗号理論 for theoretical discussions, and 暗号技術 when talking about applied cryptography.
I learned about RSA encryption in my cryptography class.
Cryptography is essential for online banking.
Specifically refers to the theoretical aspects of cryptography, such as mathematical foundations and proofs.
This paper deals with the latest advances in cryptography theory.
Focuses on the practical techniques and technologies of cryptography, often used in engineering contexts.
Cryptographic technology is the foundation of internet security.
The most common term for encryption, the process of converting plaintext into ciphertext. Often used as a noun or with する.
Data encryption is essential.
Please encrypt this file.
General term for a code or cipher. Can refer to the encrypted message itself or the system used.
They communicated using a secret code.
A more colloquial way to say 'to encrypt' or 'to put into code', though 暗号化する is more standard in technical contexts.
Let's encode this letter and send it.
The act or study of deciphering codes without the key. Often used in historical or intelligence contexts.
He was engaged in code-breaking during World War II.
A more formal term for cryptanalysis, often used in academic or technical discussions.
Cryptanalysis techniques are constantly evolving.
Often used as a shorthand for the whole field of cryptography in everyday language, though it can be ambiguous.
The history of cryptography is old.
Emphasizes the technological aspect, suitable when talking about modern applications like blockchain or secure messaging.
Thanks to cryptography, we can shop safely.
Cryptography theory researchers design new protocols.
A cryptography technology expert evaluated the system's security.
暗号 refers to codes and ciphers used for encryption, not passwords. A password is パスワード or 合言葉 (あいことば). Using 暗号 for 'password' is incorrect.
Please tell me the Wi-Fi password.
She works in cryptography research.
