# ethkey [![Build Status][travis-image]][travis-url] [travis-image]: https://travis-ci.org/paritytech/ethkey.svg?branch=master [travis-url]: https://travis-ci.org/paritytech/ethkey Ethereum keys generator. [Documentation](http://paritytech.github.io/ethkey/ethkey/index.html) ### Usage ``` Ethereum keys generator. Copyright 2016, 2017 Parity Technologies (UK) Ltd Usage: ethkey info <secret> [options] ethkey generate random [options] ethkey generate prefix <prefix> <iterations> [options] ethkey generate brain <seed> [options] ethkey sign <secret> <message> ethkey verify public <public> <signature> <message> ethkey verify address <address> <signature> <message> ethkey [-h | --help] Options: -h, --help Display this message and exit. -s, --secret Display only the secret. -p, --public Display only the public. -a, --address Display only the address. Commands: info Display public and address of the secret. generate Generates new ethereum key. random Random generation. prefix Random generation, but address must start with a prefix brain Generate new key from string seed. sign Sign message using secret. verify Verify signer of the signature. ``` ### Examples #### `info <secret>` *Display info about private key.* - `<secret>` - ethereum secret, 32 bytes long ``` ethkey info 17d08f5fe8c77af811caa0c9a187e668ce3b74a99acc3f6d976f075fa8e0be55 ``` ``` secret: 17d08f5fe8c77af811caa0c9a187e668ce3b74a99acc3f6d976f075fa8e0be55 public: 689268c0ff57a20cd299fa60d3fb374862aff565b20b5f1767906a99e6e09f3ff04ca2b2a5cd22f62941db103c0356df1a8ed20ce322cab2483db67685afd124 address: 26d1ec50b4e62c1d1a40d16e7cacc6a6580757d5 ``` -- #### `generate brain <seed>` *Generate new brain-wallet keypair using 16384 iterations.* - `<seed>` - brain-wallet seed, any string ``` ethkey generate brain "this is sparta" ``` ``` secret: 17d08f5fe8c77af811caa0c9a187e668ce3b74a99acc3f6d976f075fa8e0be55 public: 689268c0ff57a20cd299fa60d3fb374862aff565b20b5f1767906a99e6e09f3ff04ca2b2a5cd22f62941db103c0356df1a8ed20ce322cab2483db67685afd124 address: 26d1ec50b4e62c1d1a40d16e7cacc6a6580757d5 ``` -- #### `generate random` *Generate new keypair randomly.* ``` ethkey generate random ``` ``` secret: 7d29fab185a33e2cd955812397354c472d2b84615b645aa135ff539f6b0d70d5 public: 35f222d88b80151857a2877826d940104887376a94c1cbd2c8c7c192eb701df88a18a4ecb8b05b1466c5b3706042027b5e079fe3a3683e66d822b0e047aa3418 address: a8fa5dd30a87bb9e3288d604eb74949c515ab66e ``` -- #### `generate prefix <prefix> <iterations>` *Generate new keypair randomly with address starting with prefix.* - `<prefix>` - desired address prefix, 0 - 32 bytes long. - `<iterations>` - maximum number of tries before generation is assumed to be a failure. ``` ethkey generate prefix ff 1000 ``` ``` secret: 2075b1d9c124ea673de7273758ed6de14802a9da8a73ceb74533d7c312ff6acd public: 48dbce4508566a05509980a5dd1335599fcdac6f9858ba67018cecb9f09b8c4066dc4c18ae2722112fd4d9ac36d626793fffffb26071dfeb0c2300df994bd173 address: fff7e25dff2aa60f61f9d98130c8646a01f31649 ``` -- #### `sign <secret> <message>` *Sign a message with a secret.* - `<secret>` - ethereum secret, 32 bytes long - `<message>` - message to sign, 32 bytes long ``` ethkey sign 17d08f5fe8c77af811caa0c9a187e668ce3b74a99acc3f6d976f075fa8e0be55 bd50b7370c3f96733b31744c6c45079e7ae6c8d299613246d28ebcef507ec987 ``` ``` c1878cf60417151c766a712653d26ef350c8c75393458b7a9be715f053215af63dfd3b02c2ae65a8677917a8efa3172acb71cb90196e42106953ea0363c5aaf200 ``` -- #### `verify public <public> <signature> <message>` *Verify the signature.* - `<public>` - ethereum public, 64 bytes long - `<signature>` - message signature, 65 bytes long - `<message>` - message, 32 bytes long ``` ethkey verify public 689268c0ff57a20cd299fa60d3fb374862aff565b20b5f1767906a99e6e09f3ff04ca2b2a5cd22f62941db103c0356df1a8ed20ce322cab2483db67685afd124 c1878cf60417151c766a712653d26ef350c8c75393458b7a9be715f053215af63dfd3b02c2ae65a8677917a8efa3172acb71cb90196e42106953ea0363c5aaf200 bd50b7370c3f96733b31744c6c45079e7ae6c8d299613246d28ebcef507ec987 ``` ``` true ``` -- #### `verify address <address> <signature> <message>` *Verify the signature.* - `<address>` - ethereum address, 20 bytes long - `<signature>` - message signature, 65 bytes long - `<message>` - message, 32 bytes long ``` ethkey verify address 689268c0ff57a20cd299fa60d3fb374862aff565b20b5f1767906a99e6e09f3ff04ca2b2a5cd22f62941db103c0356df1a8ed20ce322cab2483db67685afd124 c1878cf60417151c766a712653d26ef350c8c75393458b7a9be715f053215af63dfd3b02c2ae65a8677917a8efa3172acb71cb90196e42106953ea0363c5aaf200 bd50b7370c3f96733b31744c6c45079e7ae6c8d299613246d28ebcef507ec987 ``` ``` true ``` # Ethcore toolchain *this project is a part of the ethcore toolchain* - [**ethkey**](https://github.com/paritytech/ethkey) - Ethereum keys generator and signer. - [**ethstore**](https://github.com/paritytech/ethstore) - Ethereum key management. - [**ethabi**](https://github.com/paritytech/ethabi) - Ethereum function calls encoding.
