tool: D366: COMMAND


tool: D518:       If the -A or -B option is specified (or assumed by default), this option


tool: D147: 


tool: D268:    pubkey - calculate and format public keys from private keys.


tool: D548: SYNOPSIS


tool: D439:    btk pubkey [INPUT_OPTIONS] [OUTPUT_OPTIONS]


tool: D132: DESCRIPTION

tool: D200:    The pubkey command generates the corresponding public key from a given


tool: D109:    private key. Input data should be a private key, or data from which a


tool: D404:    private key can be derived, in the format specified by the input option.


tool: D514:    The pubkey command will read data from standard input and interpret the


tool: D557:    format according to the input option specified. If no input option is


tool: D542:    specified, the pubkey command will read data from standard input and


tool: D28:    attempt to automatically determine the format if it can be done with a


tool: D286:    reasonable degree of certainty.


tool: D730:    The pubkey command will calculate a public key from the provided input data


tool: D17:    and print it in the format specified by the output option. If no output


tool: D351:    option is specified, the public key will be formatted as a standard


tool: D488:    bitcoin address. The public key will be compressed by default, unless


tool: D450:    the input data contains a compression flag, in which case it will remain


tool: D493:    consistent with the input data. If an output option is specified for


tool: D121:    compression, the private key will be compressed in accordance with that


tool: D262:    option, which will override any compression flag provided in the input data.


tool: D104:    See INPUT OPTIONS and OUTPUT OPTIONS for more info.


tool: D55: INPUT OPTIONS


tool: D497:    -w


tool: D222:       Treat input as a (w)allet import formatted (wif) string.


tool: D315:    -h


tool: D115:       Treat input as a (h)exadecimal formatted string. The string must be at


tool: D218:       least 64 characters long. If a 65th and 66th character exist, they are


tool: D808:       interpreted as a compression flag. Any extra characters beyond that point


tool: D11:       are ignored.


tool: D40:    -r


tool: D673:       Treat input as (r)aw binary data. Input must be at least 32 bytes long.


tool: D381:       If a 33rd byte exists, it is interpreted as a compression flag. Any


tool: D446:       extra data beyond that point is ignored.


tool: D422:    -s


tool: D322:       Treat input as an arbitrary ASCII (s)tring. ASCII strings are processed


tool: D330:       through a SHA256 hash algorithm to generate a 32 byte private key.


tool: D152:    -d


tool: D296:       Treat input as an ASCII string containing only (d)ecimal characters. The


tool: D628:       decimal value is converted to its 32-byte binary equivalent to generate


tool: D758:       a private key.


tool: D403:    -b


tool: D615:       Treat input as arbitrary (b)inary data. The data is processed through


tool: D46:       a SHA256 hash algorithm to generate a 32 byte private key.


tool: D692: OUTPUT OPTIONS


tool: D461:    -A


tool: D220:       Print public key as a traditional bitcoin (A)ddress. (default)


tool: D442:    -B


tool: D358:       Print public key as a (B)ech32 address.


tool: D487:    -H


tool: D130:       Print public key as a (H)exadecimal string. Note that a compressed


tool: D304:       public key in hexadecimal format is 66 characters long. An uncompressed


tool: D211:       public key is 130 characters long.


tool: D327:    -R


tool: D670:       Print public key as (R)aw binary data. This will result in 33 bytes for


tool: D732:       a compressed public key and 65 bytes for an uncompressed public key.


tool: D368:    -C


tool: D709:       (C)ompress the public key. If -P is specified (see below), the


tool: D279:       corresponding private key will also be compressed.


tool: D275:    -U


tool: D1:       (U)nompress the public key. If -P is specified (see below), the


tool: D513:       corresponding private key will also be uncompressed.


tool: D666:    -P


tool: D564:       Include the (P)rivate key in the output. This option is most useful for


tool: D406:       wrapper programs that want to generate and parse a private and public


tool: D464:       key pair in a single command. The private key will be printed first,


tool: D288:       followed by a single space, followed by the public key.


tool: D559:    -N


tool: D441:       Do NOT print a (N)ewline character. This may be a desirable option if


tool: D246:       the output is being parsed by a wrapper program.


tool: D788:    -T


tool: D206:       sets the (T)ESTNET prefix so the public key is usable on the TESTNET


tool: D21:       network. If the -P option is also specified, the private key will be


tool: D128:       formatted for TESTNET network.


tool: D270:    -M


tool: D491:       sets the (M)AINNET prefix so the public key can be used on the MAINNET


tool: D47:       network. Note that if no network flag is specified or included in the


tool: D320:       input data, the MAINNET prefix is used by default. This option is only


tool: D195:       useful for converting TESTNET keys to MAINNET. If the -P option is also


tool: D251:       specified, the private key will be formatted for TESTNET network.


tool: D350: See https://github.com/bartobri/bitcoin-toolkit for examples.


tool: D476: See 'btk help' to read about other commands.
