Encrypt and Decrypt files under Deno runtime

Using the Deno runtime to encrypt, compress, and recover a file.

Credit

• This package uses wasm-flate.wasm built from this repository to compress/decompress files.

• The wasm-flate module is a thin wasm wrapper around the flate2 crate.

• The aes128 encryption/decryption is done using wasm-aes-soft.asm built from this repository.

• The wasm-aes-soft module is a thin wasm wrapper around the aes-soft crate.

Encrypt a file

deno run --allow-read --allow-write encrypt.ts sample.txt

Running this will create two files:

• sample.enc.txt
• sample.key

Decrypt a file

At this point, because padding is used while decrypting, for text files one has to filter out the null character.

 deno run --allow-read --allow-write decrypt.ts sample.enc.txt sample.key true

For any other file type the last flag can be ignored.
