Hashing

8 operations. Call any of them with cyberchef_bake, or pre-load them with CYBERCHEF_TOOL_SURFACE=all.

BLAKE2b

Performs BLAKE2b hashing on the input. BLAKE2b is a flavour of the BLAKE cryptographic hash function that is optimized for 64-bit platforms and produces digests of any size between 1 and 64 bytes. Supports the use of an optional key.

• Tool name: cyberchef_blake2b
• Input / output: ArrayBuffer → string

Argument	Type	Default
size	option	512
output_encoding	option	Hex
key	toggleString	{"option":"UTF8","string":""}

BLAKE2s

Performs BLAKE2s hashing on the input. BLAKE2s is a flavour of the BLAKE cryptographic hash function that is optimized for 8- to 32-bit platforms and produces digests of any size between 1 and 32 bytes. Supports the use of an optional key.

• Tool name: cyberchef_blake2s
• Input / output: ArrayBuffer → string

Argument	Type	Default
size	option	256
output_encoding	option	Hex
key	toggleString	{"option":"UTF8","string":""}

BLAKE3

Hashes the input using BLAKE3 (UTF-8 encoded), with an optional key (also UTF-8), and outputs the result in hexadecimal format.

• Tool name: cyberchef_blake3
• Input / output: string → string

Argument	Type	Default
size_bytes	number	16
key	string	—

Convert co-ordinate format

Converts geographical coordinates between different formats.Supported formats:Degrees Minutes Seconds (DMS)Degrees Decimal Minutes (DDM)Decimal Degrees (DD)GeohashMilitary Grid Reference System (MGRS)Ordnance Survey National Grid (OSNG)Universal Transverse Mercator (UTM)The operation can try to detect the input co-ordinate format and delimiter automatically, but this may not always work correctly.

• Tool name: cyberchef_convert_co_ordinate_format
• Input / output: string → string

Argument	Type	Default
input_format	option	Auto
input_delimiter	option	Auto
output_format	option	Degrees Minutes Seconds
output_delimiter	option	Space
include_compass_directions	option	None
precision	number	3

GOST Hash

The GOST hash function, defined in the standards GOST R 34.11-94 and GOST 34.311-95 is a 256-bit cryptographic hash function. It was initially defined in the Russian national standard GOST R 34.11-94 Information Technology – Cryptographic Information Security – Hash Function. The equivalent standard used by other member-states of the CIS is GOST 34.311-95.This function must not be confused with a different Streebog hash function, which is defined in the new revision of the standard GOST R 34.11-2012.The GOST hash function is based on the GOST block cipher.

• Tool name: cyberchef_gost_hash
• Input / output: ArrayBuffer → string

Argument	Type	Default
algorithm	argSelector	GOST 28147 (1994)
digest_length	option	256
sbox	option	E-TEST

MurmurHash3

Generates a MurmurHash v3 for a string input and an optional seed input

• Tool name: cyberchef_murmurhash3
• Input / output: string → number

Argument	Type	Default
seed	number	0
convert_to_signed	boolean	false

Show on map

Displays co-ordinates on a slippy map.Co-ordinates will be converted to decimal degrees before being shown on the map.Supported formats:Degrees Minutes Seconds (DMS)Degrees Decimal Minutes (DDM)Decimal Degrees (DD)GeohashMilitary Grid Reference System (MGRS)Ordnance Survey National Grid (OSNG)Universal Transverse Mercator (UTM)This operation will not work offline.

• Tool name: cyberchef_show_on_map
• Input / output: string → html

Argument	Type	Default
zoom_level	number	13
input_format	option	Auto
input_delimiter	option	Auto

Streebog

Streebog is a cryptographic hash function defined in the Russian national standard GOST R 34.11-2012 Information Technology – Cryptographic Information Security – Hash Function. It was created to replace an obsolete GOST hash function defined in the old standard GOST R 34.11-94, and as an asymmetric reply to SHA-3 competition by the US National Institute of Standards and Technology.

• Tool name: cyberchef_streebog
• Input / output: ArrayBuffer → string

Argument	Type	Default
digest_length	option	256
