$sha512 calculates the sha512 hash of a text, binary variable, or file. Hash is 160-bits, shown as 128 lower-case hexadecimal characters.
Synopsis[edit]
$sha512(plaintext|&binaryvar|filename,[N])
Parameters[edit]
plaintext - Used with N = 0, just the string you want the sha512 hash of
&binaryvar - A binary variable, used with N = 1, return the sha512 hash of the content of the binvar
filename - A filename, used with N = 2, return the sha512 hash of the content of the file
N: Optional integer 0-2, where 0 indicates data is treated as plaintext, 1 indicates a &binary variable, 2 treats data as contents of a filename
If the N parameter isn't used, the default 0 is used (which is different than $crc which has default of N=2.)
Properties[edit]
None
Example[edit]
Echo the SHA512 hash of plain text string abc to the active window:
//echo -a $sha512(abc)
or
//echo -a $sha512(abc,0)
The DATA is case-sensitive, so hash of "abc" is different than hash of "ABC"
Echo the SHA512 hash of the zero-length null string to the active window:
//echo -a $sha512($null)
Echo the SHA512 hash of the first 1000 bytes of the mIRC program you're running to the active window:
//bread $qt($mircexe) 0 1000 &snip | echo -a $sha512(&snip,1)
Echo the SHA512 hash of the contents of the mIRC program you're running to the active window:
//echo -a $sha512($mircexe,2)
Note that because the default is N=0, $sha512($mircexe) is the SHA512 hash for the plaintext text string of the drive:\path\filename for the mIRC you're running, and not the hash of the filename contents. This differs from $crc($mircexe) giving the checksum of the filename contents because $crc has default of N=2.
mIRC v7.x Unicode-encodes bytes 128-255 to utf8 before providing to $sha512, if the text doesn't have code points above 255, you can avoid the utf8 encoding issue by using a binvar with the -a switch.
//bset -ta &string 1 chloé | echo -a $sha1(&string,1)
Error Messages[edit]
Note that $sha512 differs from $crc in that it generates error for non-existent files instead of returning hash of $null string. Also, hex string returned by $sha512 is lowercase while $crc returns uppercase hex.
* Error accessing file: $sha512
Either file does not exist, or file permissions don't allow the file to be read. i.e. $sha512(non-existent-file,2) or $sha512(c:\hiberfil.sys,2)
* Invalid parameters: $sha512
Either using a zero-length/non-existent binary variable or specifying an N where $int(%N) isn't 0-2.
Both above errors halt execution of the script
Compatibility[edit]
Added: mIRC v7.42
Added on: 17 Jul 2015
Note: Unless otherwise stated, this was the date of original functionality.
Further enhancements may have been made in later versions.
