• Cryptology - It is the science encryption, which encompasses cryptography and cryptanalysis.
• Cryptology - It refers to the study of codes, which involves both writing and solving them.
• Cryptography - it is the process of making and using codes to secure the transmission of information
• Cryptography - It is the science of secret writing to keep the data secret and an important aspect when dealing with network security
• Crypto - it means secret or hidden.
• Symmetric Key Cryptography - It involves usage of one secret key along with encryption and decryption of algorithms which help in securing the contents of the message.
• Asymmetric Key Cryptography - It is also known as public key cryptography that involves the usage of public key along with secret key.
• Hashing - It involves taking the plaintext and converting it ot has value of fixed size by a hash function.
• Cryptanalysis - It is the process of obtaining the plaintext message from a ciphertext message without knowing the keys used to perform the encryption.
