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.
