Cryptography

Cryptography (the making or solving of codes and algorithms) is the science of hiding information with the use of mathematical theories and computation to encrypt and decrypt data or to guarantee the integrity and authenticity of the information which makes it nearly impossible to tamper even if sent over an unsecured network. In a basic process of text encryption, plaintext (data that can be clearly understood) undergoes an encryption process that turns it into ciphertext (which is unreadable) but the type of security used on regular personal files (like contacts) is not the same as the one used on cryptocurrency networks.
