How to use
Use an 8–1024 character password. Text is limited to 256 KB and plaintext files to 20 MB. Encryption creates an AlphaX-AES-GCM v1 JSON envelope with PBKDF2-SHA256 at 600000 iterations, a 16-byte salt, a 12-byte IV and a 128-bit authentication tag. Metadata is authenticated; the original password is required to decrypt.
