Description of problem:

In September 2017, using openssl-1.0.2j-3.fc25.x86_64, I encrypted a file ;
 in November 2017, using openssl-1.1.0g-1.fc27.x86_64, decrypting, I get :

  bad decrypt
  140138754258752:error:06065064:digital envelope 
  routines:EVP_DecryptFinal_ex:bad decrypt:crypto/evp/evp_enc.c:569:

The file decrypts correctly with openssl-1.0.2j-1.fc24.i686.

Version-Release number of selected component (if applicable):

  openssl-1.1.0g-1.fc27.x86_64

How reproducible:

  At each attempt to decrypt.

Steps to Reproduce:

1. With openssl-1.0.2j-3.fc25.x86_64 :

   $ openssl bf -a <clear >crypted

2. With openssl-1.1.0g-1.fc27.x86_64 :

   $ openssl bf -d -a <crypted >clear

Actual results:

bad decrypt
140135393576768:error:06065064:digital envelope routines:EVP_DecryptFinal_ex:bad decrypt:crypto/evp/evp_enc.c:569:

Expected results:

  Uneventful decryption.

Additional info:

  With openssl-1.1.0g-1.fc27.x86_64, encrypted files are larger than with
openssl-1.0.2j-3.fc25.x86_64.

Just add -md md5 to the openssl 1.1.0 command line. See the HISTORY section of the enc(1) manual page.
