What is Base64 - How to Decode Base64 Encryption
Base64 is a binary-to-text encoding system that converts binary data into a radix-64 representation and then encodes it as an ASCII string. In other words, it is a technique for converting binary data into a form that can be sent over communication lines that are only intended to handle ASCII text.
Every three binary bytes are divided into four groups of six bits as part of the encoding process. A mapping table is then used to translate each 6-bit group into a corresponding ASCII character. The final character string is then transferred or saved as text.
When binary data needs to be represented as text, Base64 is frequently used in email systems to send attachments, in online applications to communicate data between the client and the server, and in other contexts. The encoded data can be easily deciphered by anyone with access to the decoding algorithm and the encoded data, making Base64 neither a type of encryption nor a secure method of data transmission.

Types of Encryption
- Symmetric encryption: With this method, the encryption and decryption operations use the same key. Advanced Encryption Standard (AES), Data Encryption Standard (DES), and Triple Data Encryption Standard are examples of symmetric encryption (3DES).
- Public-key cryptography, or asymmetric encryption, employs two separate keys for encryption and decryption. One key is available to everyone and can be shared, however, the owner must keep the other key private and secret. Elliptic Curve Cryptography, Diffie-Hellman, and RSA are examples of asymmetric encryption (ECC).
- A one-way encryption method called hashing creates a fixed-size output known as a hash. The original data cannot be recovered after the input data has been turned into a fixed-size output. Message Digest 5 (MD5) and Secure Hash Algorithm are two examples of hashing (SHA).
- Quantum cryptography secures communication channels by applying the ideas of quantum mechanics. To produce a safe encryption key, it depends on the characteristics of photons and other subatomic particles. The use of quantum encryption is still in its infancy and is not yet widespread.
- Homomorphic encryption: This method enables computations to be carried out on encrypted data without the requirement for decryption. When sensitive data needs to be studied while retaining its privacy, this is helpful. Since it is still a relatively new method, homomorphic encryption is not yet commonly employed.
- Obfuscation: By making data difficult to understand, obfuscation conceals the meaning of the data. To safeguard source code and prevent reverse engineering, it is frequently employed in the development of software. Obfuscation is a related data protection method but is not a true kind of encryption.
