tool: D934: COMMAND


tool: D1109: 


tool: D385:    pubkey - calculate and format public keys from private keys.


tool: D316: SYNOPSIS


tool: D685:    btk pubkey [INPUT_OPTIONS] [OUTPUT_OPTIONS]


tool: D580: DESCRIPTION

tool: D592:    The pubkey command generates the corresponding public key from a given


tool: D455:    private key. Input data should be a private key, or data from which a


tool: D348:    private key can be derived, in the format specified by the input option.


tool: D983:    The pubkey command will read data from standard input and interpret the


tool: D878:    format according to the input option specified. If no input option is


tool: D32:    specified, the pubkey command will read data from standard input and


tool: D625:    attempt to automatically determine the format if it can be done with a


tool: D431:    reasonable degree of certainty.


tool: D988:    The pubkey command will calculate a public key from the provided input data


tool: D999:    and print it in the format specified by the output option. If no output


tool: D182:    option is specified, the public key will be formatted as a standard


tool: D869:    bitcoin address. The public key will be compressed by default, unless


tool: D122:    the input data contains a compression flag, in which case it will remain


tool: D293:    consistent with the input data. If an output option is specified for


tool: D627:    compression, the private key will be compressed in accordance with that


tool: D57:    option, which will override any compression flag provided in the input data.


tool: D1040:    See INPUT OPTIONS and OUTPUT OPTIONS for more info.


tool: D662: INPUT OPTIONS


tool: D171:    -w


tool: D1066:       Treat input as a (w)allet import formatted (wif) string.


tool: D927:    -h


tool: D534:       Treat input as a (h)exadecimal formatted string. The string must be at


tool: D678:       least 64 characters long. If a 65th and 66th character exist, they are


tool: D157:       interpreted as a compression flag. Any extra characters beyond that point


tool: D820:       are ignored.


tool: D394:    -r


tool: D522:       Treat input as (r)aw binary data. Input must be at least 32 bytes long.


tool: D528:       If a 33rd byte exists, it is interpreted as a compression flag. Any


tool: D967:       extra data beyond that point is ignored.


tool: D726:    -s


tool: D1028:       Treat input as an arbitrary ASCII (s)tring. ASCII strings are processed


tool: D582:       through a SHA256 hash algorithm to generate a 32 byte private key.


tool: D288:    -d


tool: D937:       Treat input as an ASCII string containing only (d)ecimal characters. The


tool: D24:       decimal value is converted to its 32-byte binary equivalent to generate


tool: D252:       a private key.


tool: D95:    -b


tool: D15:       Treat input as arbitrary (b)inary data. The data is processed through


tool: D810:       a SHA256 hash algorithm to generate a 32 byte private key.


tool: D461: OUTPUT OPTIONS


tool: D863:    -A


tool: D912:       Print public key as a traditional bitcoin (A)ddress. (default)


tool: D93:    -B


tool: D664:       Print public key as a (B)ech32 address.


tool: D767:    -H


tool: D905:       Print public key as a (H)exadecimal string. Note that a compressed


tool: D23:       public key in hexadecimal format is 66 characters long. An uncompressed


tool: D827:       public key is 130 characters long.


tool: D622:    -R


tool: D502:       Print public key as (R)aw binary data. This will result in 33 bytes for


tool: D707:       a compressed public key and 65 bytes for an uncompressed public key.


tool: D708:    -C


tool: D1049:       (C)ompress the public key. If -P is specified (see below), the


tool: D1062:       corresponding private key will also be compressed.


tool: D329:    -U


tool: D762:       (U)nompress the public key. If -P is specified (see below), the


tool: D49:       corresponding private key will also be uncompressed.


tool: D362:    -P


tool: D880:       Include the (P)rivate key in the output. This option is most useful for


tool: D691:       wrapper programs that want to generate and parse a private and public


tool: D10:       key pair in a single command. The private key will be printed first,


tool: D1069:       followed by a single space, followed by the public key.


tool: D392:    -N


tool: D357:       Do NOT print a (N)ewline character. This may be a desirable option if


tool: D545:       the output is being parsed by a wrapper program.


tool: D467:    -T


tool: D245:       If the -A or -B option is specified (or assumed by default), this option


tool: D915:       sets the (T)ESTNET prefix so the public key is usable on the TESTNET


tool: D186:       network. If the -P option is also specified, the private key will be


tool: D1036:       formatted for TESTNET network.
