  1. fix: encode base64 string as a single line during encryption 

    If the encrypted string is long, the following error may occur during decryption:

```
bad decrypt
40C795C66F7F0000:error:1C800064:Provider routines:ossl_cipher_unpadblock:bad decrypt:../providers/implementations/ciphers/ciphercommon_block.c:124:
```

To prevent this error, use the -A flag during decryption.
The -A flag ensures that the Base64-encoded string is written as a single line without line breaks.
For more details, refer to the following documentation:

- [OpenSSL Base64 Encoding Documentation](https://wiki.openssl.org/index.php/Enc#Base64_Encoding)

The document notes:

> These flags tell OpenSSL to apply Base64-encoding before or after the cryptographic operation.
> The -a and -base64 are equivalent. If you want to decode a base64 file it is necessary to use the -d option.
> **By default the encoded file has a line break every 64 characters**.
> To suppress this you can use in addition to -base64 the -A flag.
> This will produce a file with no line breaks at all. You can use these flags just for encoding Base64 without any ciphers involved.
