Method Detail

• cryptoBoxKeypair

   abstract KeyPair cryptoBoxKeypair()

  Generate a secret and public key.

• cryptoBoxSeedKeypair

   abstract KeyPair cryptoBoxSeedKeypair(Array<byte> seed)

  Generate a public and secret key deterministically.

  Parameters:

  seed - The seed to generate the key.

• cryptoBoxEasy

   abstract String cryptoBoxEasy(String message, Array<byte> nonce, KeyPair keyPair)

  Encrypts a message.

  Parameters:

  message - The message.

  nonce - The nonce of size NONCEBYTES.

  keyPair - A keypair.

• cryptoBoxOpenEasy

   abstract String cryptoBoxOpenEasy(String cipherText, Array<byte> nonce, KeyPair keyPair)

  Decrypts a previously encrypted message.

  Parameters:

  cipherText - Encrypted via cryptoBoxEasy and then sodiumBin2Hex'ified.

  nonce - The nonce of size NONCEBYTES.

  keyPair - A keypair.

• cryptoBoxBeforeNm

   abstract String cryptoBoxBeforeNm(Array<byte> publicKey, Array<byte> secretKey)

  If you send several messages to the same receiver or receive several messages from thesame sender, you can gain speed by calculatingthe shared key only once, and reusing it in subsequent operations.

  Parameters:

  publicKey - A public key as generated by cryptoBoxKeypair.

  secretKey - A secret key as generated by cryptoBoxKeypair.

• cryptoBoxBeforeNm

   abstract String cryptoBoxBeforeNm(KeyPair keyPair)

  If you send several messages to the same receiver or receive several messages from thesame sender, you can gain speed by calculatingthe shared key only once, and reusing it in subsequent operations.

  Parameters:

  keyPair - A public and secret key as generated by cryptoBoxKeypair.

• cryptoBoxEasyAfterNm

   abstract String cryptoBoxEasyAfterNm(String message, Array<byte> nonce, String sharedSecretKey)

  Encrypt a message.

  Parameters:

  message - The message for encryption.

  nonce - A randomly generated nonce via nonce}.

  sharedSecretKey - The shared secret key as generated via cryptoBoxBeforeNm.

• cryptoBoxOpenEasyAfterNm

   abstract String cryptoBoxOpenEasyAfterNm(String cipher, Array<byte> nonce, String sharedSecretKey)

  Decrypt a message.

  Parameters:

  cipher - The cipher text to be decrypted.

  nonce - The same nonce used to encrypt the {@code cipher} - cryptoBoxEasyAfterNm.

  sharedSecretKey - The shared secret key as generated via cryptoBoxBeforeNm.

• cryptoBoxDetachedAfterNm

   abstract DetachedEncrypt cryptoBoxDetachedAfterNm(String message, Array<byte> nonce, String sharedSecretKey)

  Encrypt a message but allow for storage ofthe mac separately.

  Parameters:

  message - The message to encrypt.

  nonce - A randomly generated nonce via nonce}.

  sharedSecretKey - The shared secret key as generated via cryptoBoxBeforeNm.

• cryptoBoxOpenDetachedAfterNm

   abstract DetachedDecrypt cryptoBoxOpenDetachedAfterNm(DetachedEncrypt detachedEncrypt, Array<byte> nonce, String sharedSecretKey)

  Decrypt a message.

  Parameters:

  detachedEncrypt - The cipher and mac used to decrypted the message.

  nonce - The same nonce used to encrypt - cryptoBoxDetachedAfterNm}.

  sharedSecretKey - The shared secret key as generated via cryptoBoxBeforeNm.

• cryptoBoxSealEasy

   abstract String cryptoBoxSealEasy(String message, Key publicKey)

  Encrypts a message.

  Parameters:

  message - The message.

  publicKey - A public key.

• cryptoBoxSealOpenEasy

   abstract String cryptoBoxSealOpenEasy(String cipherText, KeyPair keyPair)

  Decrypts a previously encrypted message.

  Parameters:

  cipherText - Encrypted via cryptoBoxSealEasy and then sodiumBin2Hex'ified.

  keyPair - A keypair.
