Function Documentation

◆ _dbus_sha_compute()

dbus_bool_t _dbus_sha_compute ( const DBusString data,
DBusString ascii_output 
)

Computes the ASCII hex-encoded shasum of the given data and appends it to the output string.

Parameters
datainput data to be hashed
ascii_outputstring to append ASCII shasum to
Returns
FALSE if not enough memory

Definition at line 484 of file dbus-sha.c.

◆ _dbus_sha_final()

dbus_bool_t _dbus_sha_final ( DBusSHAContext context,
DBusString results 
)

SHA finalization.

Ends an SHA message-digest operation, writing the the message digest and zeroing the context. The results are returned as a raw 20-byte digest, not as the ascii-hex-digits string form of the digest.

Parameters
contextthe SHA context
resultsstring to append the 20-byte SHA digest to
Returns
FALSE if not enough memory to append the digest

◆ _dbus_sha_init()

void _dbus_sha_init ( DBusSHAContext context)

Initializes the SHA context.

Parameters
contextan uninitialized context, typically on the stack.

◆ _dbus_sha_update()

void _dbus_sha_update ( DBusSHAContext context,
const DBusString data 
)

Feeds more data into an existing shasum computation.

Parameters
contextthe SHA context
datathe additional data to hash
