Ciphertext vs. Plaintext: Know the Difference
By Shumaila Saeed || Updated on December 27, 2023
Ciphertext is encrypted text transformed from plaintext using an algorithm, making it unreadable without a key. Plaintext is unencrypted, readable text.
Key Differences
Ciphertext is the result of encrypting plaintext to secure information from unauthorized access. Plaintext is the original, unencrypted form of data, easily readable and understood.

While ciphertext provides security for sensitive data, making it inaccessible to unauthorized users, plaintext is readily accessible and comprehensible to anyone who reads it.

To create ciphertext, plaintext undergoes an encryption process using specific algorithms and keys. In contrast, plaintext requires no such process and exists in its original, unaltered state.
