public final class HashingSource extends ForwardingSource
hash()
to compute the final hash value.
In this example we use HashingSource
with a BufferedSource
to make reading
from the source easier.
HashingSource hashingSource = HashingSource.sha256(rawSource);
BufferedSource bufferedSource = Okio.buffer(hashingSource);
... // Read all of bufferedSource.
ByteString hash = hashingSource.hash();
Modifier and Type | Method and Description |
---|---|
ByteString |
hash()
Returns the hash of the bytes supplied thus far and resets the internal state of this source.
|
static HashingSource |
md5(Source source)
Returns a sink that uses the obsolete MD5 hash algorithm.
|
long |
read(Buffer sink,
long byteCount)
Removes at least 1, and up to
byteCount bytes from this and appends
them to sink . |
static HashingSource |
sha1(Source source)
Returns a sink that uses the obsolete SHA-1 hash algorithm.
|
static HashingSource |
sha256(Source source)
Returns a sink that uses the SHA-256 hash algorithm.

Warning: This method is not idempotent. Each time this method is called its internal state is cleared. This starts a new hash with zero bytes supplied.
