Decrypt extracts the nonce from the ciphertext, and attempts to decrypt with NaCl's secretbox.

DecryptFile recovers a secured blob from a file, returning a byte slice for parsing by the caller.

DeriveKey applies Scrypt with very strong parameters to generate an encryption key from a passphrase and salt.

DeriveKeyStrength applies Scrypt using the given work parameters to generate an encryption key from a passphrase and salt.

Encrypt generates a random nonce and encrypts the input using NaCl's secretbox package.

EncryptFile securely stores the encoded blob under the filename.

GenerateKey returns a randomly generated secretbox key.

KeySize contains the size (in bytes) of a NaCl secretbox key.

KeySize contains the size (in bytes) of a NaCl secretbox key.

ScryptInteractive mode uses N=2^14, r=8, p=1.

ScryptStandard mode uses N=2^20, r=8, p=2.

ScryptMode represents the work factor to be used for passphrases.
