Blockchain Cryptography for Developers: ECC, secp256k1, SCrypt, AES, Wallets

April 15, 2018
Recently I had a talk about the basics of cryptography for blockchain developers at the Bulgarian Web Summit 2018. I am happy to succeed to introduce the most important concepts of the elliptic curve cryptography (ECC), key derivation and encryption (SCrypt, AES and HMAC), digital signatures (ECDSA, sign / verify) and crypto-wallets (HD wallets, mnemonics

Online AES Encryption Tool

December 26, 2011
Few day ago I needed a JavaScript AES implementation (the Rijndael advanced encryption algorithm) which I can test instantly in my Web browser (two fields “text” and “password” and “encrypt” button). I searched for “online AES tool” but found nothing that is ready-to-use so I needed to write one. For those who need instant online
