**Cryptography** is the study of conversion of plain text(readable format) to ciphertext(non-readable format) i.e. encryption. It is also called the **study of encryption**.

**Cryptology**, on the other hand, is the study of the conversion of plain text to ciphertext and vice versa. It is also called the **study of encryption and decryption**.

One major difference is that Cryptology is the parent of Cryptography.

Let’s see the other differences.

Sl no. | Cryptography | Cryptology |
---|---|---|

1. | Cryptography is the process of conversion of plain text to cipher text. | Cryptology Is the process of conversion of plain text to cipher text and vice versa. |

2. | It is also called the study of encryption | It is also called the study of encryption and decryption. |

3. | It takes place on the sender side | It takes place on the sender and receiver side |

4. | In Cryptography, sender sends the message to receiver. | In Cryptology, both sender and receiver send messages to each other. |

5. | Cryptography can be seen as the child of Cryptology | Cryptology can be seen as the parent of Cryptography |
