While I'm debugging I saw this method return false: openssl_decrypt() in:

\phpseclib\Crypt\Base::decrypt
vendor/phpseclib/phpseclib/phpseclib/Crypt/Base.php:1084

I'm not quite sure what is wrong.

Can it be because of this OpenSSL version?

$ php -i | grep 'OpenSSL\|openssl'

SSL Version => OpenSSL/3.0.2
libSSH Version => libssh/0.9.6/openssl/zlib
openssl
OpenSSL support => enabled
OpenSSL Library Version => OpenSSL 3.0.2 15 Mar 2022
OpenSSL Header Version => OpenSSL 3.0.2 15 Mar 2022
Openssl default config => /usr/lib/ssl/openssl.cnf
openssl.cafile => no value => no value
openssl.capath => no value => no value
Native OpenSSL support => enabled

I had the same issue today. I found out the php mcrypt library was not installed.

I just installed it on my server using apt install php7.4-mcrypt

Now installation worked perfectly

The solution of @shoaibpnp worked for me as well.

Thanks!
