The crypto component hosts all the implementations of cryptographic primitives we use in Plasma: hashing, signing, and key derivation/generation. Different implementations of cryptographic algorithms are needed by users to meet specific requirements for the compliance of cryptography with standards and legislation adopted in different jurisdictions. Plasma provides sets of cryptographic primitives: secp256k1, Curve25519 (ED25519 with X25519 keys) Example of Key Structure: Account: <plasmawallet> - 2 and 12 characters in length. The characters can include a-z, 1-5, and optional dots (.) except the first and last characters.
