Free Bitcoin Address Generator (Educational)
Educational Bitcoin key generator. Generates a random private key, WIF encoding, and a simulated P2PKH Bitcoin address. Learn how Bitcoin addresses are derived with step-by-step explanation.
Bitcoin Address Generator
Educational tool that demonstrates how Bitcoin P2PKH addresses are derived from private keys using Base58Check encoding.
Educational Purposes Only
This tool does not use real secp256k1 elliptic curve derivation (which requires a native library). The Bitcoin address shown is a simulated P2PKH-format address for learning purposes and should never be used for real funds. The private key and WIF encoding are cryptographically real, but the address derivation step is approximated.

How Real Bitcoin Address Derivation Works
Generate Private Key
A cryptographically random 256-bit (32-byte) number is generated. This is your secret key — anyone with this can spend your coins.
Derive Public Key (secp256k1)
The private key is multiplied by the secp256k1 generator point G using elliptic curve multiplication. This is a one-way function — you cannot reverse it to find the private key.
Hash the Public Key
SHA-256 is applied to the public key, then RIPEMD-160 is applied to the result. This 20-byte hash is the "public key hash" (PKH).
Add Version Byte
A version byte (0x00 for mainnet P2PKH) is prepended to the PKH. This identifies the address type and network.
Compute Checksum
SHA-256 is applied twice to the versioned payload. The first 4 bytes of the result are the checksum, used to detect typos.
Base58Check Encode
The versioned payload + checksum is encoded in Base58 (no 0, O, I, l to avoid confusion). The result is the Bitcoin address starting with "1".
Bitcoin Address Types
P2PKH (Legacy)
Starts with 1
Pay-to-Public-Key-Hash. The original Bitcoin address format. Widely supported but higher fees due to larger transaction size.
0x00P2SH
Starts with 3
Pay-to-Script-Hash. Used for multisig wallets and SegWit-wrapped addresses. More flexible than P2PKH.
0x05Bech32 (SegWit)
Starts with bc1
Native SegWit addresses. Lower transaction fees, better error detection. Uses Bech32 encoding instead of Base58Check.
witness v0About Base58Check Encoding
Base58Check is the encoding scheme used for Bitcoin addresses and WIF private keys. It is Base58 (no ambiguous characters: 0, O, I, l) plus a 4-byte checksum derived from a double SHA-256 hash.
The checksum allows wallets to detect if an address was mistyped or corrupted — if even one character is wrong, the checksum will not match and the wallet will reject it.
WIF = Base58Check(0x80 + privkey + 0x01)
P2PKH address = Base58Check(0x00 + RIPEMD160(SHA256(pubkey)))
Checksum = SHA256(SHA256(payload))[0:4]
Frequently Asked Questions
Can I use the generated address for real Bitcoin?
No. The address uses an approximated derivation (SHA256 of private key instead of secp256k1 elliptic curve) and is for educational purposes only. Never send real funds to it.
Is the private key generated securely?
Yes. The private key uses crypto.getRandomValues() which is a cryptographically secure random number generator. The WIF encoding is also correct.
What is WIF format?
Wallet Import Format is a Base58Check-encoded representation of a Bitcoin private key with a version byte (0x80) and a compression flag, making it easy to import into wallets.
What is P2PKH?
Pay-to-Public-Key-Hash is the original Bitcoin address format, starting with "1". The address encodes a hash of the public key with Base58Check encoding.
