Original：🇺🇸 English

Translated

SOPS and age encryption for secrets management in git repositories. Use when: (1) Setting up encrypted secrets in a project (initial .sops.yaml configuration) (2) Encrypting/decrypting YAML, JSON, ENV, or INI files with age keys (3) Managing age keys (generation, distribution, rotation) (4) Configuring path-based encryption rules for different environments (5) Integrating SOPS decryption in CI/CD pipelines (GitHub Actions, GitLab CI) (6) Troubleshooting SOPS decryption failures or key issues (7) Selective encryption with encrypted_regex patterns

SOPS + age Secrets Management

Encrypt secrets in git with SOPS using age keys. Values are encrypted with AES256-GCM; keys are simple X25519 keypairs.

Quick Reference

Task	Command
Generate age key	`age-keygen -o keys.txt`
Extract public key	`age-keygen -y keys.txt`
Encrypt file	`sops encrypt file.yaml > file.enc.yaml`
Decrypt file	`sops decrypt file.enc.yaml`
Edit encrypted file	`sops edit file.enc.yaml`
Update recipients	`sops updatekeys -y file.enc.yaml`
Rotate data key	`sops rotate -i file.enc.yaml`

Initial Setup

1. Generate Keys

bash

# Create key directory
mkdir -p ~/.config/sops/age

# Generate keypair
age-keygen -o ~/.config/sops/age/keys.txt
# Output: public key: age1abc123...

2. Create .sops.yaml

At repository root:

yaml

creation_rules:
  - age: age1yourpublickeyhere...

3. Encrypt First File

bash

sops encrypt config/secrets.yaml > config/secrets.enc.yaml
rm config/secrets.yaml
git add config/secrets.enc.yaml .sops.yaml

Core Workflows

Encrypt New File

bash

# Create plaintext file
cat > secrets.yaml << 'EOF'
database:
  password: secret123
api_key: abc-xyz
EOF

# Encrypt (uses .sops.yaml rules)
sops encrypt secrets.yaml > secrets.enc.yaml
rm secrets.yaml

Edit Encrypted File

bash

# Opens decrypted in $EDITOR, re-encrypts on save
sops edit secrets.enc.yaml

Decrypt for Use

bash

# To stdout
sops decrypt secrets.enc.yaml

# To file
sops decrypt secrets.enc.yaml > secrets.yaml

# Extract single value
sops decrypt --extract '["database"]["password"]' secrets.enc.yaml

Pass to Process (No File)

bash

# As environment variables
sops exec-env secrets.enc.yaml './deploy.sh'

# As temporary file
sops exec-file secrets.enc.yaml 'source {}'

Multi-Environment Configuration

yaml

# .sops.yaml
creation_rules:
  # Production - admin + CI only
  - path_regex: ^config/secrets/prod\..*
    age: >-
      age1admin...,
      age1cicd...

  # Staging/Dev - broader access
  - path_regex: ^config/secrets/.*
    age: >-
      age1admin...,
      age1cicd...,
      age1dev...

Selective Encryption

Only encrypt sensitive keys (keeps file readable):

yaml

creation_rules:
  - age: age1...
    encrypted_regex: ^(password|secret|token|key|api_key|private)$

Result:

yaml

database:
  host: localhost           # plaintext
  password: ENC[AES256_GCM,data:...,type:str]  # encrypted

CI/CD Integration

GitHub Actions

yaml

- name: Decrypt secrets
  env:
    SOPS_AGE_KEY: ${{ secrets.SOPS_AGE_KEY }}
  run: sops decrypt config/secrets.enc.yaml > secrets.yaml

Store

AGE-SECRET-KEY-1...

in repository secrets as

SOPS_AGE_KEY

Environment Variables

bash

# Key file location
export SOPS_AGE_KEY_FILE=/path/to/keys.txt

# Key value directly (CI/CD)
export SOPS_AGE_KEY="AGE-SECRET-KEY-1..."

Key Management

Add New Recipient

Update
```
.sops.yaml
```
with new public key
Re-encrypt existing files:
bash
```
sops updatekeys -y file.enc.yaml
```

Remove Recipient

Remove from
```
.sops.yaml
```

Re-encrypt and rotate:

bash

sops updatekeys -y file.enc.yaml
sops rotate -i file.enc.yaml

Key Locations

Platform	Default Path
Linux	`~/.config/sops/age/keys.txt`
macOS	`~/Library/Application Support/sops/age/keys.txt`

Reference Files

File	When to Read
age-keys.md	Key generation, storage, distribution patterns
sops-config.md	.sops.yaml syntax, path rules, key groups
cli-reference.md	Full command reference, all flags
ci-cd-patterns.md	GitHub Actions, GitLab CI, Docker integration
troubleshooting.md	Common errors and solutions

Common Issues

Problem	Solution
"could not decrypt data key"	Wrong key - check `SOPS_AGE_KEY_FILE` or key location
"no matching keys found"	File uses Shamir key groups - need multiple keys
`.sops.yaml` not found	Run from repo root or ensure file is in parent directory
path_regex not matching	Use regex syntax ( `.\.yaml$` ), not glob ( `.yaml` )

Security Notes

Never commit private keys - Add
```
keys.txt
```
,
```
*.agekey
```
to
```
.gitignore
```
Use dedicated CI keys - Easier to rotate, limit scope
Rotate data keys - Run
```
sops rotate
```
periodically
Limit recipients - Production files should have minimal access
