AES encrypt then Base64 encode

When sending encrypted data through a channel that only accepts text (JSON fields, HTTP headers, URL parameters), you must encode the raw ciphertext. This chain first AES-encrypts the plaintext with your key, then Base64-encodes the binary ciphertext, producing a string safe to embed in any text medium.

What it solves

Encrypt plaintext with AES and encode the ciphertext as Base64 for text-safe transport.

Input → Output

AES Encryptor input → Base64 Encoder output across 2 steps.
