Functions

func GeneratePassphrase 

func GeneratePassphrase(numBytes int) (string, error)

GeneratePassphrase creates a cryptographically secure passphrase. The passphrase is URL-safe base64 encoded (no padding) for easy handling.

func GenerateRawPassphrase added in v0.0.8 

func GenerateRawPassphrase(numBytes int) (raw []byte, passphrase string, err error)

GenerateRawPassphrase creates random bytes and returns both the raw bytes and the base64url-encoded passphrase string. Protocol v2 splits the raw bytes via Shamir (instead of the encoded string), then base64url-encodes after recombining. The passphrase string is used for age encryption.

func HashFile 

func HashFile(path string) (string, error)

HashFile returns the SHA-256 hash of a file, prefixed with "sha256:". This function requires file system access and is not available in WASM.
