Hi experts, According to the code in apps/dgst.c, command dgst should have an option "-hmac", which means use HMAC algorithm. For openssl-0.9.8g, the code is from line 193 to line 198.However, I can not find the usage of -hmac option either in man-page or in the usage-prompt printed when user types unknown option.I tested -hmac option and found that it really works. The following is the log file:# cat testabcabc# openssl sha1 -hmac 123 testabcHMAC-SHA1(testabc)= 3af0523a2c75b5d26cc2edbf850672e9160c15b0# I think this option is missed in man-page and in the usage-prompt.Would you please check it?
