May 13, 2017 ECDSA SHA256 hash of either the private key, CSR or X509 value to file is good, while the on screen rendering indicates errors. #3457 tedescn opened this issue May 13, 2017 1 comment tedescn commented May 13, 2017.
- The RSA key pair uses modulus n whose length is k bytes. For instance, if the key is said to have length '2048 bits', then this means that 2 2047 hash it with a hash function, e.g. This yields a sequence of bytes with a fixed length, 32 bytes.
- What we get out of that operation is a pair (x, y) denoting a point on the curve, our public key. From the public key to a Bitcoin address. We’re almost there! Now we just need to turn that ECDSA public key into a standard Bitcoin address. The process is the same as point 4, executed on the SHA256+RIPEMD160 hash of the packed x and y values.
- HMAC user-input keys that are longer than the specific hash algorithms blocksize are first shortened. (By running the long keys through the hash. And then using that hash as the actual key.) SHA256 outputs 256 bit hashes. That's 32 bytes. So I suggest you generate 256 bit HMAC secret keys. (Using a cryptographically secure random generator.).
All Bitcoin private keys is simply an integer between number 1 and 115792089237316195423570985008687907852837564279074904382605163141518161494337 or HEX: from 1 to 0xfffffffffffffffffffffffffffffffebaaedce6af48a03bbfd25e8cd0364141. The integer range of valid private keys is governed by the secp256k1 ECDSA standard used by Bitcoin.
We just generate a range of these integers in sequence, divide into pages and add to our URL:
For example: http://www.AllPrivateKeys.com/1157920892373161954235709850086879078528375642790749043826051631415181614942

For more convenient using, we convert private key number to WIF format.
WIF is an abbreviation of Wallet Import Format (known as Wallet Import/ Export Format). WIF simplifies import/ export of a private key.
In order to make copying of private keys less prone to error, Wallet Import Format may be utilized. WIF uses base58Check encoding on a private key, greatly decreasing the chance of copying error, much like standard Bitcoin addresses.
- Take a private key.
- Add a 0x80 byte in front of it for mainnet addresses.
- Append a 0x01 byte after it if it should be used with compressed public keys. Nothing is appended if it is used with uncompressed public keys.
- Perform a SHA-256 hash on the extended key.
- Perform a SHA-256 hash on result of SHA-256 hash.
- Take the first four bytes of the second SHA-256 hash; this is the checksum.
- Add the four checksum bytes from point 5 at the end of the extended key from point 2.
- Convert the result from a byte string into a Base58 string using Base58Check
The process is easily reversible, using the Base58 decoding function, and removing the padding.
A compressed address is just the way of storing a public key in fewer bytes (33 instead of 65). There are no compatibility or security issues because they are precisely the same keys, just stored in a different way. The original Bitcoin software didn't use compressed keys only because their use was no disadvantages other than that a little bit of additional computation is needed to validate a signature.

Can Google crowl all pages and compromise private keys ?
Theoretically, some private keys and Bitcoins addresses can be vulnerable, because Google search engine (Bing, Yandex etc...) can index some pages with private keys and addresses. But indexing all the pages is a huge array of keys.
For example: one of our pages with 100 addresses is about 40 978 Bytes. Try to divide the number of all the addresses into 100 (rows per page), multiply by 40 978 Bytes and divide into 137438953472 (one TerraByte).
