This service allows you to verify the integrity of downloaded files by calculating its checksum.
A checksum is a way to ensure that a file has not been altered in any way from the original version.
Many websites provide checksums along with their setup files so that you can be sure of the integrity of the file.
This tool only works on the recent version of Firefox
, Chrome and Opera
and calculates the most commonly used file checksum algorithms:
- MD5
The MD5 (Message Digest) algorithm produces a 128-bit (16-byte) hash value, typically expressed in text format as a 32 digit hexadecimal number.
- SHA1
SHA1 (Secure Hash Algorithm) algorithm produces a 160-bit (20-byte) hash value, typically expressed in text format as a 40 digit hexadecimal number.
- SHA224
SHA224 (Secure Hash Algorithm) algorithm produces a 224-bit (28-byte) hash value, typically expressed in text format as a 56 digit hexadecimal number.
- SHA256
SHA256 (Secure Hash Algorithm) algorithm produces a 256-bit (32-byte) hash value, typically expressed in text format as a 64 digit hexadecimal number.
- SHA384
SHA384 (Secure Hash Algorithm) algorithm produces a 384-bit (48-byte) hash value, typically expressed in text format as a 96 digit hexadecimal number.
- SHA512
SHA512 (Secure Hash Algorithm) algorithm produces a 512-bit (64-byte) hash value, typically expressed in text format as a 128 digit hexadecimal number.
- RIPEMD160
RIPEMD160 (RACE Integrity Primitives Evaluation Message Digest) algorithm produces a 160-bit (20-byte) hash value, typically expressed in text format as a 40 digit hexadecimal number.
The file you upload and the calculated hash will never be sent to the server. All calculations are performed directly in the browser using Javascript.
