Functions

  • decrypt
    Decrypts the ciphertext with the given password and returns the plaintext.
  • encrypt
    Encrypts the plaintext with the given password and returns the ciphertext. The nonce is generated at each call to strengthen the encryption. Otherwise there’s a chance the key is weakened if the same nonce is used. The nonce is 24 byte (following the XCHACHA_NONCESIZE property). The ciphertext will be 40 bytes longer than the plaintext because of the XCHACHA_NONCESIZE + POLY1305_OUTSIZE size.
