Example:
tcp-request connection track-sc0 src,debug(track-sc)
+digest(<algorithm>)
+ Converts a binary input sample to a message digest. The result is a binary
+ sample. The <algorithm> must be an OpenSSL message digest name (e.g. sha256).
+
+ Please note that this converter is only available when haproxy has been
+ compiled with USE_OPENSSL.
+
div(<value>)
Divides the input value of type signed integer by <value>, and returns the
result as an signed integer. If <value> is null, the largest unsigned
this converter is used, the input integer value is first casted to an
unsigned 32-bit integer.
+hmac(<algorithm>, <key>)
+ Converts a binary input sample to a message authentication code with the given
+ key. The result is a binary sample. The <algorithm> must be one of the
+ registered OpenSSL message digest names (e.g. sha256). The <key> parameter must
+ be base64 encoded and can either be a string or a variable.
+
+ Please note that this converter is only available when haproxy has been
+ compiled with USE_OPENSSL.
+
http_date([<offset],[<unit>])
Converts an integer supposed to contain a date since epoch to a string
representing this date in a format suitable for use in HTTP header fields. If
