Functions
`` |  | generateRSAKey(bits, implementations=['openssl', 'python']) `Generate an RSA key with the specified bit length. @type bits: int @param bits: Desired bit length of the new key's modulus. @rtype: L{tlslite.utils.RSAKey.RSAKey} @return: A new RSA private key.` parseAsPublicKey(s) `Parse an XML or PEM-formatted public key. @type s: str @param s: A string containing an XML or PEM-encoded public or private key. @rtype: L{tlslite.utils.RSAKey.RSAKey} @return: An RSA public key. @raise SyntaxError: If the key is not properly formatted.` parsePEMKey(s, private=False, public=False, passwordCallback=None, implementations=['openssl', 'python']) `Parse a PEM-format key. The PEM format is used by OpenSSL and other tools. The format is typically used to store both the public and private components of a key.

TLS Lite can only handle password-encrypted private keys when OpenSSL and M2Crypto are installed. In this case, passwordCallback will be invoked to query the user for the password. @type s: str @param s: A string containing a PEM-encoded public or private key. @type private: bool @param private: If True, a L{SyntaxError} will be raised if the private key component is not present. @type public: bool @param public: If True, the private key component (if present) will be discarded, so this function will always return a public key. @type passwordCallback: callable @param passwordCallback: This function will be called, with no arguments, if the PEM-encoded private key is password-encrypted. The callback should return the password string. If the password is incorrect, SyntaxError will be raised. If no callback is passed and the key is password-encrypted, a prompt will be displayed at the console. @rtype: L{tlslite.utils.RSAKey.RSAKey} @return: An RSA key. @raise SyntaxError: If the key is not properly formatted.` parsePrivateKey(s) `Parse an XML or PEM-formatted private key. @type s: str @param s: A string containing an XML or PEM-encoded private key. @rtype: L{tlslite.utils.RSAKey.RSAKey} @return: An RSA private key. @raise SyntaxError: If the key is not properly formatted.` parseXMLKey(s, private=False, public=False, implementations=['python']) `Parse an XML-format key. The XML format used here is specific to tlslite and cryptoIDlib. The format can store the public component of a key, or the public and private components.
