DER signature, in v || DER format. SECG!SEC1 strict DER with low S, as described in BIP62/66, BIP146, EIP2. 'v' is 1 byte in size. 'v' represents the parity bit of 'r' and can be either 0 or 1.
RAW signature, in v || r || s format. 'v' is 1 byte in size, and 'r' and 's' are each 32 bytes in size. 'v' represents the parity bit of 'r' and can be either 0 or 1.
BIP340 Signature - Schnorr 64 bytes.
RFC-6979 standard deterministic ECDSA signature. DER type in the format v || DER, with 'v' having a size of 1 byte. 'v' is the parity bit of 'r' and can have the values 0 or 1
RFC-6979 standard deterministic ECDSA signature. RAW type in the format v || r || s, with 'v' having a size of 1 byte and 'r' and 's' each having a size of 32 bytes. 'v' is the parity bit of 'r' and can have the values 0 or 1.
