Salt (16B) + IV (12B) are random per encryption and packed into the Base64 output.

PBKDF2-SHA256 applies 100k iterations and random 16-byte salt, then AES-GCM encrypts with fresh IV. For illustration, Hello with pass123 yields Base64 bundle holding salt and IV within one hundred milliseconds, while 50KB notes lock near two hundred milliseconds. Fresh randomness per message thwarts pattern analysis across archives.
No. Key stretching and encryption execute solely inside this tab through WebCrypto without transmission. For instance, Hello World trials remain resident. The tool is fully client-side; your input is never logged or uploaded. Avoid production passwords on shared machines; employ test phrases for learning exercises.
Yes. Operation proceeds after load without servers; for example, encrypt Hello with pass123 to obtain Base64 with salt and IV. Decrypt by pasting back with identical password to verify return. Hashing alternatives live at /hash-generator, while robust keys originate at /password-generator for stronger protection.
Unique salts prevent rainbow precomputation across users, while unique IVs stop identical plaintexts producing identical ciphertexts that leak patterns. For example, encrypting Hello twice yields distinct Base64 due to fresh values. Reusing IVs in GCM catastrophically exposes authentication keys, so this tool generates cryptographically random values per operation automatically.
Encryption secures wording with password-derived AES-256-GCM and PBKDF2, salt and IV for confidential messaging. Example 1: Hello with pass123 produces Base64 bundle within one hundred milliseconds. Example 2: 50KB notes lock near two hundred milliseconds with distinct ciphertext each run. Random salt and IV per message prevent reuse detection. Unlike Base64 at /base64-tool which merely encodes visibly, AES provides genuine secrecy with authentication. Developers share sensitive notes, store vault exports and demonstrate cryptography without server exposure across training sessions.
Reference protection table: PBKDF2 100k stretches passwords | 16-byte salt randomizes keys | random IV randomizes ciphertext | GCM tag detects tampering | same Hello yields different Base64 | wrong password fails authentication. Stretching slows brute force, salt defeats rainbow tables. Edge case: weak pass123 still falls to guessing despite sound primitives, demanding lengthy passphrases. Copy bundle holding salt and IV for decryption, safeguard passwords separately, and trial decryption immediately to confirm correctness before transmitting bundles. Clinics testing weak pass123 versus Correct-Horse-9 quantify stretching benefits through timed crack demos that motivate passphrase adoption across teams while updating policy guides quarterly now daily and posters.
Type Hello World, set Correct-Horse-9, press Encrypt, copy Base64 bundle, paste back with same password to verify return. Second trial: encrypt identical Hello twice to observe differing outputs proving freshness. Limitation: password distribution remains out of scope, huge 5MB notes may hesitate on handsets, so chunk them. For integrity without secrecy, see the maker at /hash-generator for digests. For robust secrets, see the maker at /password-generator for generation.
