# Hashing algorithms (i.e. digest algorithms) operate on raw bytes.
# Therefore, we must specify the character encoding (utf-8, utf-16, iso-8859-1, etc.) to be used when hashing.

# Get the SHA256 hash in hex
sha256_hex = sb.getHash("sha256","hex","utf-8")
print "SHA256: " + sha256_hex + "\n";

# Get the SHA384 hash in hex lowercase
sha384_hex = sb.getHash("sha384","hex_lower","utf-8")
print "SHA384: " + sha384_hex + "\n";

# Get the SHA512 hash in base64
sha512_base64 = sb.getHash("sha512","base64","utf-8")
print "SHA512: " + sha512_base64 + "\n";

# Get the SHA1 hash in hex lowercase
sha1_hex = sb.getHash("sha1","hex_lower","utf-8")
print "SHA1: " + sha1_hex + "\n";

# Get the CRC8 digest in decimal
crc8_decimal = sb.getHash("crc8","decimal","utf-8")
print "CRC8: " + crc8_decimal + "\n";
