rc4-set-key

Arguments: key-data &key start end external-format

rc4-set-key initializes the stream cipher context based on the key data. key-data can be a string or an usb8 (i.e. (unsigned-byte 8)) vector. If it is a string, then it will be internally converted to an usb8 vector according to the external-format keyword argument (or the default external format, if the keyword argument is not supplied). The start and end keyword arguments indicate the subset of key-data that will be used as the key (as if with subseq). start defaults to 0 and end defaults to the length of key-data. If key-data is a string, then start/end are in terms of characters, otherwise, they are in terms of bytes.

This function returns a fresh rc4 key context which should be used in subsequent calls to the rc4 function.

See MD5, SHA1, HMAC, and RC4 support in miscellaneous.htm.
