Unlocking Secrets: How Key Encryption Works

In a world where data is considered the new oil, ensuring the confidentiality and security of this priceless resource is paramount. As an industry pioneer, Togggle is committed to safeguarding data through cutting-edge decentralized KYC (Know Your Customer) processes. In today’s post, we’ll explore the fascinating world of key encryption, which is at the heart of ensuring data privacy and security. From symmetric to asymmetric encryption, we’ll unveil the secrets behind these sophisticated technologies that keep our digital identities and information safe.

Before diving into the depths of key encryption, it’s essential to understand what it entails. Key encryption is the process of encoding information so that only authorized parties can access it. It uses algorithms and cryptographic keys to transform plaintext (readable data) into ciphertext (encoded data). Only those with the proper key can decipher the ciphertext back into plaintext.

Why Is Key Encryption Important?

With the rising threats of cyberattacks and data breaches, key encryption is no longer an option but a necessity. In the context of Togggle’s decentralized KYC, it ensures that customer data is only accessible to verified entities, thus maintaining integrity and trust.

In symmetric encryption, a single key is used for both encrypting and decrypting information. Imagine a locked box that can be secured and unlocked with the same key; this is how symmetric encryption functions.

Popular Symmetric Encryption Algorithms
  • AES (Advanced Encryption Standard): This is a widely-used algorithm known for its robustness and speed. It's used in various applications, including securing file storage and communications.
  • DES (Data Encryption Standard): DES was one of the earliest encryption algorithms. However, due to its shorter key length, it's now considered less secure compared to more modern algorithms.
  • Triple DES: To counter the vulnerabilities of DES, Triple DES applies the DES algorithm three times to each data block.
  • Faster than asymmetric encryption
  • Requires less computational power
  • If the key is compromised, the data is vulnerable
  • Key distribution can be a challenge

Asymmetric encryption, also known as public-key cryptography, uses two different keys – a public key and a private key. The public key is open to anyone, while the private key is kept secret. Information encrypted with the public key can only be decrypted with the associated private key and vice versa.

Well-Known Asymmetric Encryption Algorithms

  • RSA (Rivest-Shamir-Adleman): One of the first public-key cryptosystems, RSA is widely used for secure data transmission and digital signatures.
  • ECC (Elliptic Curve Cryptography): ECC is gaining popularity for its ability to provide the same level of security as RSA but with much shorter key lengths, making it faster and more efficient.


  • More secure as the private key is never shared
  • Facilitates digital signatures and authentication


  • Slower than symmetric encryption
  • Requires more computational power

Hybrid Encryption: Best of Both Worlds

In practice, both symmetric and asymmetric encryption are often used together in what’s known as hybrid encryption. This combines the speed of symmetric encryption with the security of asymmetric encryption.

  1. Key Exchange: Parties exchange public keys and keep their private keys secret.
  2. Symmetric Key Generation and Encryption: A symmetric key is generated and used to encrypt the data.
  3. Asymmetric Encryption of the Symmetric Key: The symmetric key is then encrypted with the recipient’s public key.
  4. Transmission and Decryption: The encrypted data and encrypted symmetric key are sent to the recipient. The recipient uses their private key to decrypt the symmetric key and then uses this symmetric key to decrypt the data.

This process combines the advantages of both encryption methods, providing a fast and secure way to transmit data.
