FAQs

1. What is cryptography?

Cryptography is the science and practice of securing communication and information by transforming it into an unreadable format, known as ciphertext, using mathematical algorithms and cryptographic keys. The primary purpose of cryptography is to ensure the confidentiality, integrity, and authenticity of data. Here's a breakdown of its key components:

Confidentiality: Cryptography prevents unauthorized access to sensitive information. When data is encrypted, it becomes unreadable without the correct decryption key. Only authorized parties with the appropriate key can decipher and access the original content.

Integrity: Cryptography helps ensure the integrity of data, meaning that it has not been tampered with or altered during transmission or storage. Any unauthorized changes to the encrypted data would render it undecipherable.

Authentication: Cryptography provides a means to verify the authenticity of the sender and receiver of data. Digital signatures, a cryptographic technique, allow individuals and systems to confirm the identity of the sender and verify that the message has not been altered in transit.

Non-Repudiation: Cryptographic techniques like digital signatures also provide non-repudiation, meaning that a sender cannot deny the authenticity of their message or transaction.

Data Protection: Cryptography safeguards data at rest (stored data) and data in transit (data being transmitted over networks). It is a critical component of cybersecurity, protecting information from unauthorized access and eavesdropping.

Cryptography relies on complex mathematical algorithms that transform plaintext (readable data) into ciphertext and back again. These algorithms are designed to be computationally difficult to reverse without the correct cryptographic key, ensuring that even if an attacker gains access to the ciphertext, they cannot easily decipher it.

The field of cryptography is constantly evolving to keep pace with advances in computing and the ever-changing landscape of cybersecurity threats. Cryptographers work to develop new cryptographic techniques, algorithms, and protocols to strengthen security and protect sensitive information in an increasingly digital world.

2. Can I become a cryptographer without a degree?
