Function Documentation

◆ aes_decrypt()

static secure_buffer aes_decrypt	(	const secure_buffer &	text,
		const secure_buffer &	key
	)

static

Same as aes_encrypt(), except of course it takes encrypted data as an argument and returns decrypted data.

Definition at line 379 of file credentials.cpp.

References DBG_CFG, ERR_CFG, i, utils::join(), and secure_buffer::secure_buffer().

Referenced by preferences::load_credentials(), and preferences::password().

◆ aes_encrypt()

static secure_buffer aes_encrypt	(	const secure_buffer &	plaintext,
		const secure_buffer &	key
	)

static

Encrypts the value of plaintext using key and a hard coded IV using AES.

Max size of plaintext must not be larger than 1008 bytes.

NOTE: This is not meant to provide strong protections against a determined attacker. This is meant to hide the passwords from malware scanning files for passwords, family/friends poking around, etc.

Parameters

plaintext	The original unencrypted data.
key	The value to use to encrypt the data. See build_key() for key generation.

Returns: secure_buffer The encrypted data.

Definition at line 288 of file credentials.cpp.

References DBG_CFG, ERR_CFG, i, utils::join(), and secure_buffer::secure_buffer().

◆ build_key()

secure_buffer build_key	(	const std::string &	server,
		const std::string &	login
	)

static

Fills a secure_buffer with 32 bytes of deterministically generated bytes, then overwrites it with the system login name, server login name, and server name.

If this is more than 32 bytes, then it's truncated. If it's less than 32 bytes, then the pre-generated bytes are used to pad it.
