+The credential is split into a set of named attributes, with one

 specified by a key-value pair, separated by an `=` (equals) sign,
 followed by a newline. The key may contain any bytes except `=`,
 newline, or NUL. The value may contain any bytes except newline or NUL.
 In both cases, all bytes are treated as-is (i.e., there is no quoting,
 and one cannot transmit a value with newline or NUL in it). The list of
 attributes is terminated by a blank line or end-of-file.
