Vulnerable: It is also susceptible to cryptographic attacks, such as brute-force attacks, that can compromise the security of encrypted data. Requiring a high skill: Cryptography requires a high degree of skill, knowledge, and resources to implement ... WebCryptography provides for secure communication in the presence of malicious third-parties—known as adversaries. Encryption uses an algorithm and a key to transform an input (i.e., plaintext) into an encrypted output (i.e., ciphertext). A given algorithm will always transform the same plaintext into the same ciphertext if the same key is used.
