Uses of CryptoException in org.drasyl.crypto

Methods in org.drasyl.crypto that throw CryptoException

Modifier and Type	Method	Description
KeyAgreementPublicKey	Crypto.convertIdentityKeyToKeyAgreementKey(IdentityPublicKey publicKey)	Converts the given ed25519 long time publicKey into a curve25519 key for (on-demand) key agreement.
KeyPair<KeyAgreementPublicKey,KeyAgreementSecretKey>	Crypto.convertLongTimeKeyPairToKeyAgreementKeyPair(KeyPair<IdentityPublicKey,IdentitySecretKey> keyPair)	Converts the given ed25519 long time keyPair into a curve25519 key pair for (on-demand) key agreement.
byte[]	Crypto.decrypt(byte[] cipher, byte[] authTag, Nonce nonce, SessionPair sessionPair)	Decrypt the given cipher, by verify the authTag as an authentication tag, uses the given nonce and decrypting with the rx part of the sessionPair.
byte[]	Crypto.encrypt(byte[] message, byte[] authTag, Nonce nonce, SessionPair sessionPair)	Encrypts the given message, by adding authTag as an authentication tag, using the given (hopefully fresh) nonce and encrypting with the tx part of the sessionPair.
KeyPair<KeyAgreementPublicKey,KeyAgreementSecretKey>	Crypto.generateEphemeralKeyPair()	Generates a new curve25519 key pair for key exchange.
KeyPair<IdentityPublicKey,IdentitySecretKey>	Crypto.generateLongTimeKeyPair()	Generates a new ed25519 key pair for signing and on-demand encryption.
<P extends PublicKey, S extends SecretKey> SessionPair	Crypto.generateSessionKeyPair(KeyPair<P,S> myKeyPair, PublicKey receiverPublicKey)	Generates session key pair from the myKeyPair and receiverKeyPair.
byte[]	Crypto.sha256(byte[] input)	Generates a SHA-256 hash of the given input.
byte[]	Crypto.sign(byte[] message, IdentitySecretKey secretKey)	Creates a signature for the given message with the given secretKey in detached mode (signature is not appended to message, rather it is standalone).
