By now, due to the great flexibility that the md5_gen format provides, I was able to simply add them in the john.conf file whereas my previous patches were written in C. But the last format I want to add is SHA-1($p), having $p encoded in UTF-16LE format. sha1 support is still experimental but with the last of the jumbo patches, utf-16le encoding is supported for md5. Do I have to implement a full module, mixing utf conversion functions from unicode.c and rawsha1_fmt ? I tried this in the configuration file, but the test failed : Flag=MGF_KEYS_UNICODE_B4_CRYPT Flag=MGF_SHA1_40_BYTE_FINISH Func=MD5GenBaseFunc__clean_input Func=MD5GenBaseFunc__append_keys Func=MD5GenBaseFunc__SHA1_crypt_input1_to_output1_FINAL Test vectors can be easily obtained with those lines of python: import hashlib hashlib.sha1("password".encode("UTF-16LE")).hexdigest() Thanks. J-Michel
