I am trying to move a backup and decrypt it.
# openssl enc -aes-256-cbc -d -in daily_db_2021-11-08_03h00m_Monday.sql.gz.enc -out daily_db_2021-11-08_03h00m_Monday.sql.gz
enter aes-256-cbc decryption password:
*** WARNING : deprecated key derivation used.
Using -iter or -pbkdf2 would be better.
bad decrypt
140497360426304:error:06065064:digital envelope routines:EVP_DecryptFinal_ex:bad decrypt:../crypto/evp/evp_enc.c:610:
Runing with -nopad option to openssl doesn't result in an error but I still can not read the resulting file.
# openssl enc -aes-256-cbc -d -in daily_db_2021-11-08_03h00m_Monday.sql.gz.enc -out daily_db_2021-11-08_03h00m_Monday.sql.gz -nopad
enter aes-256-cbc decryption password:
*** WARNING : deprecated key derivation used.
Using -iter or -pbkdf2 would be better.
# zcat daily_db_2021-11-08_03h00m_Monday.sql.gz | head
gzip: daily_db_2021-11-08_03h00m_Monday.sql.gz: not in gzip format
The resulting file is something but not gz.
# ls -lah daily_db_2021-11-08_03h00m_Monday.sql.gz
-rw-r--r-- 1 root root 3.1M Nov 8 14:09 daily_db_2021-11-08_03h00m_Monday.sql.gz
Encryption settings on my server:
# Do you wish to encrypt your backups using openssl?
CONFIG_encrypt='yes'
# Choose a password to encrypt the backups.
CONFIG_encrypt_password='***'
AutoMySQLBackup version 3.0
OpenSSL on both ends:
