Function Documentation

◆ aesDecrypt()

OPENDHT_PUBLIC Blob dht::crypto::aesDecrypt	(	const Blob &	data,
		const Blob &	key
	)

AES-GCM decryption.

◆ aesEncrypt()

OPENDHT_PUBLIC Blob dht::crypto::aesEncrypt	(	const Blob &	data,
		const Blob &	key
	)

AES-GCM encryption. Key must be 128, 192 or 256 bits long (16, 24 or 32 bytes).

◆ generateIdentity()

OPENDHT_PUBLIC Identity dht::crypto::generateIdentity	(	const std::string &	name,
		Identity	ca,
		unsigned	key_length,
		bool	is_ca
	)

Generate an RSA key pair (4096 bits) and a certificate.

Parameters

name	the name used in the generated certificate
ca	if set, the certificate authority that will sign the generated certificate. If not set, the generated certificate will be a self-signed CA.
key_length	stength of the generated private key (bits).

◆ hash()

OPENDHT_PUBLIC Blob dht::crypto::hash	(	const Blob &	data,
		size_t	hash_length = `512/8`
	)

Performs SHA512, SHA256 or SHA1, depending on hash_length. Attempts to choose an hash function with output size of at least hash_length bytes, Current implementation will use SHA1 for hash_length up to 20 bytes, will use SHA256 for hash_length up to 32 bytes, will use SHA512 for hash_length of 33 bytes and more.

◆ stretchKey()

OPENDHT_PUBLIC Blob dht::crypto::stretchKey	(	const std::string &	password,
		Blob &	salt,
		size_t	key_length = `512/8`
	)

Generates an encryption key from a text password, making the key longer to bruteforce. The generated key also depends on a unique salt value of any size, that can be transmitted in clear, and will be generated if not provided (32 bytes).
