Is there a difference between both terms?
The word Crypto is mostly used Data security and Encryption field, in which we use different data security techniques to secure our data whether it's video, audio, image or whatsoever. So i think crypto and cryptocurrency do have different meanings. How? Crypto is used to secure every data but "Cryptocurrency is used to secure transactional data related to money or to validate the transactions of digital money. That's why we use the word Cryptocurrency and sometimes we use Crypto as the abbreviation of Cryptocurrency.
Sir, decodx, has mentioned many synonyms of Crypto but each of those words has a different meaning according to the field in which they are being used.
Cryptography
Cryptogram
Cryptology
Cryptovirology
Cryptosphere
Cryptography --> is used to make secure communication between two or multiple parties by establishing an encrypted channel.
Cryptogram-->It's the word used to encrypt messages using puzzle of codes and cipher text to encrypt it, so that when someone (third person) get access to it then he/she could not decrypt it as it will be protected with codes.
Cryptology--> this has the same function as Cryptogram but it goes a little deep into the design and origin of rules and principles for deep encryption of data. overall the purpose is the same: to encrypt Data. It is similar to Cryptography.
Cryptovirology-->It's used to make malware and malicious software using encryption methods so that they can easily be put into the victim's computer or any digital device to get control of it. Overall, data encryption and security techniques are used in this field too.
Cryptosphere--> is the study in which data encryption and techniques are used to encrypt transactional data of money (digital). It's the same as Cryptology, cryptography, and cryptocurrency but to some extent. Like crypto sphere is the field of study like getting access to journals, research papers, and books.
Overall, if we see among these different words, one thing we will see as common is "encryption of important Data so that no one can tamper with it" same is happening in Cryptocurrency and crypto. So, Crypto is a word used to broadly cover all the fields of data encryption and security but Cryptocurrency is mainly used for encryption and security of Transactional data of Digital money.
