SHA512JS.create()
-----------------------------------------------------------
return : container
create a container to calculate SHA512 hash
SHA512JS.init(cnt)
-----------------------------------------------------------
cnt : container
return : undefined (nothing)
initialize container
SHA512JS.updateByByteArray(cnt, bytearray, offset, length)
-----------------------------------------------------------
cnt : container
bytearray : 8bit integer array
offset : array index offset
length : using array data count
return : undefined (nothing)
calculate SHA512 hash by byte array data
SHA512JS.updateByByteString(cnt, string, offset, length)
-----------------------------------------------------------
cnt : container
bytearray : string (use lower 8bit of character code)
offset : string index offset
length : using character count
return : undefined (nothing)
calculate SHA512 hash by string
SHA512JS.updateByNumberArray(cnt, numarray, offset, length, bits)
-----------------------------------------------------------
cnt : container
numarray : integer array (16bit integer or 32bit integer) *as Big Endian
offset : array index offset
length : using array data count
bits : integer bits (16 or 32)
return : undefined (nothing)
calculate SHA512 hash by integer array as big endian
SHA512JS.updateByNumberArrayLE(cnt, numarray, offset, length, bits)
-----------------------------------------------------------
cnt : container
numarray : integer array (16bit integer or 32bit integer) *as Little Endian
offset : array index offset
length : using array data count
bits : integer bits (16 or 32)
return : undefined (nothing)
calculate SHA512 hash by integer array as little endian
SHA52JS.finish(cnt)
-----------------------------------------------------------
cnt : container
return : undefined (nothing)
you must call this method when reached to end of all data to update
this method writes finite flag, zero and bits count, finally calculate hash
SHA512JS.getHash(cnt, bytearry, offset)
-----------------------------------------------------------
cnt : container
bytearray : array to copy 64 8bit-integers of hash
offset : array index offset
return : undefined (nothing)
copy SHA512 hash data(64bytes) to array
SHA512JS.toHexString(cnt)
-----------------------------------------------------------
cnt : container
return : hex-number-character string (length 128)
make SHA512 hash string (convert each bytes to 2-hex-number-charecter string[0-9a-f])
SHA512JS.toByteString(cnt)
-----------------------------------------------------------
cnt : container
return : string (length 64)
make SHA512 data byte-string (convert each bytes to character code[0-255])
be careful, this string includes unvisible character code
SHA512JS.getHashToNumberArray(cnt, bits, numarray, offset)
-----------------------------------------------------------
cnt : container
bits : integer bits (16 or 32)
numarray : integer array to copy to hash (pack Big Endian)
offset : array index offset
return : undefined (nothing)
copy SHA512 hash data(64bytes) to integer array (16bit or 32bit) (pack big endian)
be careful, argument bits position is difference position of updateByNumberArray
SHA512JS.getHashToNumberArrayLE(cnt, bits, numarray, offset)
-----------------------------------------------------------
cnt : container
bits : integer bits (16 or 32)
numarray : integer array to copy to hash (pack Little Endian)
offset : array index offset
return : undefined (nothing)
copy SHA512 hash data(64bytes) to integer array (16bit or 32bit) (pack little endian)
be careful, argument bits position is difference position of updateByNumberArrayLE
