Keep your data secured over an insecure public network. Let’s dive deeper into cryptography, how it works, and how to use crypto encryption with the Postman API Platform.
Modern cryptography techniques include algorithms and ciphers that enable theencryptionand decryption of information, such as 128-bit and 256-bit encryption keys. Modernciphers, such as the Advanced Encryption Standard (AES), are considered virtually unbreakable. A common cryptography definition is the p...

In the digital era, the goal of cryptography remains the same: to prevent information exchanged between two parties being swiped by an adversary. Computer scientists often refer to the two parties as “Alice and Bob,” fictional entities first introduced in a 1978 article describing a digital en...
The word comes from the Greek word "kryptos," meaning 'secret' or 'hidden.' The literal translation for cryptography is "secret writing." It comes from the study of cryptology, the art of breaking codes or ancient hieroglyphics and solving them. Data encryption is one of the most important...
A widely used form of public key cryptography, called RSA encryption, taps into the tricky nature of prime factorization – finding two prime numbers that multiply together to give you a specific solution. Multiplying two prime numbers takes no time at all, but even the fastest computers on Ear...
Cryptography vs encryption The difference between cryptography and encryption is that while cryptography can be broadly defined as the science of sending secret messages, encryption is the specific process of converting data into code. While encryption is an integral part of cryptography, it is just ...
Single-key or symmetric-key encryptionalgorithmscreate a fixed length of bits known as ablock cipherwith a secret key that the creator/sender uses to encipher data (encryption) and the receiver uses to decipher it. One example ofsymmetric-key cryptographyis the Advanced Encryption Standard (AES)...
With symmetric cryptography, the same key is used for both encryption and decryption. A sender and a recipient must already have a shared key that is known to both. Key distribution is a tricky problem and was the impetus for developing asymmetric cryptography. ...
In asymmetric encryption cryptography, one public and one private key are used to encrypt and decrypt data. Thepublic keycan be disseminated openly, while theprivate keyis known only to the owner. In this method, a person can encrypt a message using the receiver’s public key, but it can ...
