Functions

func Argon2KeyGen

func Argon2KeyGen(password string, salt []byte, keyLen int) ([]byte, error)

Argon2KeyGen returns an encoded string generation of a key generated using the go crypto argon2 impl specifically, the Argon2id version, a "hybrid version of Argon2 combining Argon2i and Argon2d."

func GenerateSalt

func GenerateSalt(size int) ([]byte, error)

GenerateSalt generates a random salt value for a given size

func GetKeyIDFromJWT

func GetKeyIDFromJWT(token keyaccess.JWT) (string, error)

func GetMethodForDID

func GetMethodForDID(did string) (didsdk.Method, error)

GetMethodForDID gets a DID method from a did, the second part of the did (e.g. did:test:abcd, the method is 'test')

func Is2xxResponse

func Is2xxResponse(statusCode int) bool

Is2xxResponse returns true if the given status code is a 2xx response

func IsStructPtr

func IsStructPtr(obj any) bool

IsStructPtr checks if the given object is a pointer to a struct

func ParseJWT

func ParseJWT(token keyaccess.JWT) (*jws.Signature, jwt.Token, error)

ParseJWT parses a JWT token and returns the jws signature and jwt claims

func SanitizeLog

func SanitizeLog(log string) string

SanitizeLog prevents certain classes of injection attacks before logging https://codeql.github.com/codeql-query-help/go/go-log-injection/

func XChaCha20Poly1305Decrypt

func XChaCha20Poly1305Decrypt(key, data []byte) ([]byte, error)

XChaCha20Poly1305Decrypt takes a 32 byte key and uses XChaCha20-Poly1305 to decrypt a piece of data

func XChaCha20Poly1305Encrypt

func XChaCha20Poly1305Encrypt(key, data []byte) ([]byte, error)

XChaCha20Poly1305Encrypt takes a 32 byte key and uses XChaCha20-Poly1305 to encrypt a piece of data
