Detailed Description

The key was not set on an object. This occurs with symmetric objects where an operation which requires the key is called prior to set_key being called.

Member Function Documentation

◆ error_code()

virtual int Botan::Exception::error_code ( ) const

Return an error code associated with this exception, or otherwise 0.

The domain of this error varies depending on the source, for example on POSIX systems it might be errno, while on a Windows system it might be the result of GetLastError or WSAGetLastError. For error_type() is OpenSSLError, it will (if nonzero) be an OpenSSL error code from ERR_get_error.

Reimplemented in Botan::System_Error, Botan::Compression_Error, Botan::OpenSSL_Error, Botan::CommonCrypto_Error, Botan::TLS::TLS_Exception, and Botan_FFI::FFI_Error.

Definition at line 103 of file exceptn.h.

103 { return 0; }

◆ error_type()

ErrorType Botan::Key_Not_Set::error_type ( ) const

Return the "type" of error which occurred.

Reimplemented from Botan::Invalid_State.

Definition at line 222 of file exceptn.h.

References Botan::KeyNotSet.

◆ what()

const char* Botan::Exception::what ( ) const

Return a descriptive string which is hopefully comprehensible to a developer. It will likely not be useful for an end user.

The string has no particular format, and the content of exception messages may change from release to release. Thus the main use of this function is for logging or debugging.
