A real-world example

version:1+expdate:4+cryptomoduleId:1+length:1+timeInterval:1+bankId:1+seed:20+name:~14

Field	Length	Value	Binary
version	1	1	\x01
expireDate	4	220101	\x00\x03\x5b\xc5
cryptomoduleId	1	1	\x01
bankId	1	2	\x02
length	1	4	\x4
time_interval	1	60	\x3c
seed	20	abcdefghijklmnopqrst	\x61\x62\x63\x64\x65\x66\x67\x68\x69\x6a\x6b\x6c\x6d\x6e\x6f\x70\x71\x72\x73\x74
name	14	abcdefghijklmn	\x61\x62\x63\x64\x65\x66\x67\x68\x69\x6a\x6b\x6c\x6d\x6e

After bundling:

\x01\x00\x02\xe7\x06\x01\x04<\x02abcdefghijklmnopqrstabcdefghijklmn

After adding checksum

\x01\x00\x02\xe7\x06\x01\x04<\x02abcdefghijklmnopqrstabcdefghijklmn5540

After encrypt with IV=abcdefghijklmnop and secret=abcdefghijklmnopqrstuvwxyz123456

abcdefghijklmnop\x17\x05\xb3\xe0\x0f\xd3Qcb\r\xd9\x90\x15\x1dr\xf4&\x19\xee\xf5\x15\xd2\\\x08\xbe\xd9OD\x91\xbc

@masoodkamyab Is the secret in bind response a URL safe base64?

[pylover]

@hamedaakhlaghi, Yes all base64 encoded tokens are url-encoded base64:

    def to_dict(self):
        return dict(
            name=self.name,
            secret=base64.urlsafe_b64encode(self.secret),
        )

@masoodkamyab Is this issue closed and is it final?

[EhsanMashhadi]

Where are otpLength and timeInteral?

@EhsanMashhadi

Sorry,

These information was missed in the description above:

version:1+expdate:4+cryptomoduleId:1+length:1+timeInterval:1+bankId:1+seed:20+name:~14

[masoodkamyab]

@EhsanMashhadi I update the table and add enumerators to mobile-token-isc this URL

[EhsanMashhadi]

I should mention that from the above sample:
expire date = 220101 = 2022/01/01
