pub fn sha256_bytes(&self, input_buf: &[u8]) -> String

Returns a sha256 of the supplied byte slice.

C-API equivalent

olm_sha256

Panics

• OUTPUT_BUFFER_TOO_SMALL for supplied output buffer
• on malformed UTF-8 coding of the hash provided by libolm

pub fn sha256_utf8_msg(&self, msg: &str) -> String

Convenience function that converts the UTF-8 message to bytes and then calls sha256_bytes(), returning its output.

pub fn ed25519_verify(
    &self,
    key: &str,
    message: &str,
    signature: String
) -> Result<bool, OlmUtilityError>

Verify a ed25519 signature.

Arugments

• key - The public part of the ed25519 key that signed the message.
• message - The message that was signed.
• signature - The signature of the message.
