For signatures, consider ECDSA (same curves than for ECDH) or RSA with a large enough key and PKCS#1 padding (v1.5 or PSS). WebAsymmetric cryptography, also known as public-key cryptography, is a process that uses a pair of related keys -- one public key and one private key -- to encrypt and decrypt a message and protect it from unauthorized access or use. phosphoric acid suppliers south africa
