WebFeb 11, 2016 · 2 There are lots of security algorithms. One of the way to measure security of a cryptography algorithm is to find out its key size. There are many key size of a single algorithm. ECC (Elliptic Curve Cryptography) has 163, 256, 384, 512 etc. RSA has 1024, 3072, 7680, 15360. I found this from here but how can I calculate key size of an algorithm? WebThe science of encrypting and decrypting information is called cryptography. In computing, unencrypted data is also known as plaintext, and encrypted data is called ciphertext. The formulas used to encode and decode messages are called encryption algorithms, or ciphers. To be effective, a cipher includes a variable as part of the algorithm.
