Function Documentation

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:
data input data to be hashed
ascii_output string to append ASCII shasum to
Returns:
FALSE if not enough memory

Definition at line 482 of file dbus-sha.c.

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:
context the SHA context
results string to append the 20-byte SHA digest to
Returns:
FALSE if not enough memory to append the digest

void _dbus_sha_init DBusSHAContext context  ) 
 

Initializes the SHA context.

Parameters:
context an uninitialized context, typically on the stack.

void _dbus_sha_update DBusSHAContext context,
const DBusString data
 

Feeds more data into an existing shasum computation.

Parameters:
context the SHA context
data the additional data to hash
