Document

Returns a hash function implementing the SHA-1 algorithm (160 hash bits) by delegating to the SHA-1 MessageDigest .

Usage

From source file:com.google.collide.dtogen.DtoGenerator.java

private static String getApiHash(File interfaceJar) throws IOException {
    byte[] fileBytes = Files.toByteArray(interfaceJar);
    HashCode hashCode = Hashing.sha1().hashBytes(fileBytes);
    return hashCode.toString();
}
